Learning Ada
Frequently Asked Questions (FAQ)

Recent changes to this FAQ are listed in the first section after the table of contents. This document is under explicit copyright.

Introduction

This is a list of resources to learn Ada. This list includes interactive tutorials, books, source code collections, etc.

Ada is an advanced, modern programming language, designed and standardized to support and strongly encourage widely recognized software engineering principles: reliability, portability, modularity, reusability, programming as a human activity, efficiency, maintainability, information hiding, abstract data types, genericity, concurrent programming, object-oriented programming, etc.

All validated Ada compilers (i.e. a huge majority of the commercial Ada compilers) have passed a controlled validation process using an extensive validation suite. Ada is not a superset or extension of any other language. Ada does not allow the dangerous practices or effects of old languages, although it does provide standardized mechanisms to interface with other languages such as Fortran, Cobol, and C.

Ada is recognized as an excellent vehicle for education in programming and software engineering, including for a first programming course.

Ada is defined by an international standard (the language reference manual, or LRM), which has been revised in 1995. Ada is taught and used all around the world (not just in the USA). Ada is used in a very wide range of applications: banking, medical devices, telecommunications, air traffic control, airplanes, railroad signalling, satellites, rockets, etc.

3: Are there computer-based Ada tutorials?

There are many ways to learn Ada.

Here are some on-line Ada tutorials expressly designed for self-study:

  1. Lovelace is a free (no charge) self-directed Ada 95 tutorial available on the World Wide Web (WWW), at http://www.adahome.com/Tutorials/Lovelace/lovelace.html

    Lovelace assumes that the user already knows some other algorithmic programming language (such as C, C++, or Pascal). Lovelace is interactive; it contains a number of short sections, and most short sections end with a question (to help ensure that you've understood the section's material). Lovelace can be used directly from the WWW (see above), downloaded from http://www.adahome.com/Tutorials/Lovelace/download.html

    or run from a CD-ROM, described at http://ftp.cdrom.com/titles/ada.html

    Lovelace was developed by David A. Wheeler.

  2. Learn Ada on the Web (LAW) by Dr. Fintan Culwin was developed to freely provide Ada training on the World Wide Web, at URL http://www.scism.sbu.ac.uk/law/lawhp.html

    LAW is concerned with initial software development education rather than with helping programmers who already know other computer languages. Also, LAW is concerned as much with providing software engineering tools over the Web as with presenting information regarding Ada. Dr. Culwin believes that the Lovelace and LAW projects are complementary rather than needless duplication of each other, since their target users are so different.

    LAW includes an interesting capability to interactively create Ada programs remotely over the Web; you might want to use this LAW capability even if you choose to use another tutorial.

    Dr. Culwin is at South Bank University, London, and may be contacted at fintan@vax.sbu.ac.uk

  3. Coronado Enterprises Tutorials are shareware tutorials. Their tutorial of interest to us is an Ada 83 tutorial located at http://www.swcp.com/~dodrill/adalist.html
    (the suggested fee is US$15)

  4. The C/C++ Programmers Ada Tutorial is a short hypertext tutorial, located at http://www.adahome.com/Ammo/cpp2ada.html

    for programmers who have a C or C++ style programming language background. It was written by Simon Johnson, with some additional text by Tucker Taft.

  5. Ada-Tutr is a shareware interactive Ada tutor developed by John Herro of Software Innovations Technology. You can download it from the Ada-Tutr web site, at http://members.aol.com/AdaTutor/sit.htm

    or the Ada-Tutr ftp site, located at ftp://members.aol.com/AdaTutor/sit.htm

    You can also download it by calling the SaddleBag BBS, 1-407-773-0831, and log in with the name Ada Tutor and the password tutor. The Public Ada Library's copy of Ada-Tutr (mirror) is another way to retrieve Ada-Tutr. There is also an older version of Ada-Tutr for Ada 83 (mirror). AdaTutr has a number of exercises that give a more complete understanding of Ada but will take more time to complete than a tutor without such exercises (such as Lovelace).

  6. HOT_Ada, a two-volume course/tutorial distributed on floppy disks, is available from Stage Harbor Software; it is not directly available via the WWW. It does not include a compiler. It is similar to a set of tutorial slides, except for the hyper-linking features and the fact that you can proceed at your own pace and accommodate your own learning style and needs.

    HOT_Ada is designed for individual, self-paced learning. One version runs on Macintoshes, another on PCs with Windows. The many hypertext and hypergraphic features allow you, for instance, to click on a "hot word" to see its definition in the Glossary or click on a "hot icon" in a diagram to jump to the corresponding line of Ada source code in a previously hidden listing.

    The regular price is $29 for a single volume, $49 for the two-volume set.

    E-mail inquiries welcomed at: bscrawford@aol.com. Regular mail inquiries or mail orders (specify Mac or Windows, personal checks accepted) can be sent to:

    	 Stage Harbor Software
    	 9 Patriots Drive
    	 Lexington, MA 02173
    

    What does the course cover?

    HOT_Ada is a two-volume course/tutorial, distributed on floppy disks. Volume 1, the "core" part of the course, provides a pictorial introduction to object technology (OOA and OOD presented in a language-independent manner) and a pictorial introduction to Ada 9X, with emphasis on its OOP features. Volume 2 provides an extended case study with a step-by-step illustration of the OOA, OOD and OOP concepts outlined in Volume 1. A mixture of classification and composition approaches is illustrated. The OOA and OOD material is strongly influenced by the Fusion Method, a fusion of OMT, Booch, Coad-Yourdon, et al. HOT_Ada is designed for individual, self-paced learning. One version runs on Macintoshes. Another version runs on PC's with Windows. There are many hypertext and hypergraphic features. For example, you can click on a "hot word" to see its definition in the Glossary, or click on a "hot icon" in a diagram to jump to the corresponding line of Ada source code in a previously hidden listing. A major theme of the course is the reuse of patterns and parts.

    Who can benefit from HOT_Ada?

    Several categories of people can benefit from self-study using HOT_Ada. If you are familiar with Ada 83, and have begun to study Ada 9X, you can supplement other efforts by reviewing this picture-based material and the case study. If, as an Ada software engineer, you want to learn more about object technology in general, especially the Fusion approach, HOT_Ada provides an ideal combination for learning and "tying it all together." If you are a newcomer to Ada, the visual approach of HOT_Ada may provide you with an excellent way to start your learning process -- to be followed up using traditional text and classroom methods.

    What are the System Requirements?

    How to Order by Mail?

    Write a personal check for $49 to Stage Harbor Software and mail it to Stage Harbor Software, 9 Patriots Drive, Lexington, MA 02173. Be sure to specify the Windows or Mac version of HOT_Ada, and include your e-mail address if you have one. (Credit card orders are not accepted.)

Here are some other Ada-related educational materials that you may find helpful:

  1. Introducing Ada95 is a set of slides about Ada 95 by Richard Conn, released without restrictions on its use and distribution. Here's a quote from Richard Conn:

    This is a day-long short course that introduces Ada95. The purpose of the course is to explore the Ada95 language, including its facilities for object-oriented design and programming, real-time programming, distributed processing, and other domains. The course will concentrate on the practical aspects of applying the features of Ada95 to the software development process. Numerous examples of the language are presented.

    Richard Conn's tutorial is available in Zipped Powerpoint Postscript format. (736K). A README file accompanies the tutorial.

    Free viewers for both Macintosh (602K) and PCs running Windows (1,092K) are available for those who do not own Powerpoint.

  2. Ada 95: The Next Generation, a slide set by Mike Kamrad, is available through the SIGAda server. It is available in both Powerpoint 4.0 for the Macintosh format (140K) and Powerpoint 4.0 for Windows format (84K). Free viewers for both Macintosh (602K) and PCs running Windows (1,092K) are available for those who do not own Powerpoint.

  3. ASSET maintains a collection of Ada-related courseware; see ASSET's WWW page for more information.

  4. Other PAL Courseware (mirror) products are available by FTP (in addition to AdaTutr and Lovelace, listed above). Walnut Creek mirrors the PAL onto its Ada CD-ROM. A copy of the Ada CD-ROM is available on-line.

  5. An "Academic Ada" package developed by Intermetrics and Aonix is available for Windows 95/NT.

Group 1: Books Suitable for
a First Course in Programming with Ada 95

Ada: A Developmental Approach
Fintan Culwin
Prentice Hall Europe, 1997 (ISBN 0-13-264680-3)

As its title suggests, this is essentially an introduction to software development, using Ada. This interesting book, intended for novice programmers, has a major virtue: it stresses the importance of design and does not pretend that software engineering issues can be ignored while one is learning to create programs.

The book covers most major issues of software development: modularity, component-based programming, levels of abstractions, ADTs, design tools (Booch and JSP), user interface aspects, white/black box testing, debugging, documentation, object-oriented programming, programming by contract and formal specifications, and metrics. Simultaneously, the reader is introduced to the mechanisms of Ada 95, thus learning in context about program structure, selection, iteration, recursion; data types, structures, and files; algorithms and complexity; polymorphism, heterogeneous data structures, and generics.

Due to the number of topics found in the book, the software engineering issues are not dealt with in details, but the novice programmer will be armed with a general understanding of what skills he needs to master in order to become a professional software developer.

There are five section, with a total of 34 chapters. A few exercises are proposed at the end of the chapters; no solutions are provided in the book. Unfortunately there are frequent typographical errors in the text, WWW resources are often inaccurately cited, and formatting of the code examples is awkward --which can make them difficult to read. Concurrency is not covered.

The LAW project (Learning Ada on the Web) contains a collection of resources directly supporting the book, including a draft of the complete text and an additional section (omitted for reasons of space), all the source code, a list of errata, and more. (M.K.)

Ada 95: The Craft of Object-Oriented Programming
John English
Prentice Hall Europe, 1996 (ISBN 0-13-230350-7)

This book introduces Ada-as-a-first-language, using an example-driven approach that gradually develops small programs into large case studies. Even for one who already knows Ada, it is a pleasure to read, especially as it emphasizes an object-oriented perspective on the development of Ada applications.

The reader is quickly introduced to "high-level" mechanisms, such as exception handling and the hierarchical library. Interestingly, the author systematically creates his examples in a namespace hierarchy rooted at a package aptly named "JE".

The book is very well-written and appropriately stresses many software engineering concerns throughout the 20 chapters; for instance, maintenance scenarios are used to underscore the essential design choices faced at various stages of development. Four annexes summarize the syntax of the language and essential predefined entities. Tasking is described, but not in detail. (M.K.)


Ada 95: Problem Solving and Program Design
Michael Feldman and Elliot Koffman
Addison-Wesley, 1996 (ISBN 0-201-30485-6)

As with the earlier edition by the same authors, the first 2/3 of the book is suitable as a CS1 text with Ada as the language of instruction, and the the last few chapters, combined with some language-independent algorithm theory, cover the rest of the Ada langauge in sufficient depth to serve as the language-specific basis of a CS2 course.

The style is like that of a musical fugue: sections that develop general programming and problem solving techniques are interleaved with sections that develop successively larger subsets of the Ada 95 language and libraries; examples recur from one chapter to another, in progressively more completely developed forms. Packages are introduced from the start; other language features are introduced very gradually at first and then at a progressively faster pace. Loops come up in chapter 5, records and arrays by chapter 8, generics by chapter 11, and pointers, tagged types, and tasks in chapters 14-16. The nearly 200 examples have all been compiled and tested, and are available in electronic format from the first author, the Addison Wesley home page, and the usual Ada archives. (T.B.)

The book is packaged with a CD-ROM which contains a special edition of the Aonix ObjectAda compiler for Windows NT/95 (useable for student projects; limited to 2000 lines per source file, 20 tasks per program, and 35 program units per program).

Prof. Feldman has made available online the full Instructor's Manual for this book,
URL http://www.seas.gwu.edu/faculty/mfeldman/cs1-im/


Ada from the Beginning, 3rd ed.
Jan Skansholm
Addison-Wesley, 1997 (ISBN 0-201-40376-5)

This book was one of the first to use Ada with CS1-style pedagogy. There are excellent sections on the idiosyncracies of interactive I/O (a problem in all languages), and a sufficient number of fully-worked examples to satisfy students. Generics, linked lists and recursion are covered at the end; there is no tasking coverage, but one would not expect this at CS1-level. A very interesting addition is the new Chapter 14, in which OOP in both Ada 83 and Ada 95 is discussed. This is an especially lucid explanation of OOP in Ada, and makes a real contribution because it doesn't just discuss tagged types as a "feature" of Ada 95, but shows very nicely what is possible in Ada 83 (instead of just what is not possible), and shows how Ada 95 adds functionality. (M.B.F.)

The 2nd edition was published before the Ada 95 standard was finalized, but this 3rd edition fully takes into account the Ada 95 standard.


Group 2: Books on Specific Topics,
with Ada 95 as the Language of Discourse

Data Structures and Algorithms: An Object-Oriented Approach Using Ada 95
John Beidler
Springer-Verlag, 1997 (ISBN 0-387-94834-1)
(CS2/data structures)

This book introduces classical data structures and algorithms, with a strong emphasis on object-orientation. Abstraction, encapsulation, representation, iterators, and basic measurements form the cornerstone of the presentation. Structures cover: stacks, queues, lists, trees, graphs, sets and strings; algorithms cover: sorting and searching. The writing style is informal, almost like a narrative. The book assumes a basic knowledge of Ada. The 12 chapters each end with suggestions for exercises and further explorations. Contains a bibliography and an index. The software components are available over the Internet.

Prof. Beidler has made available online the software components described in his book,

Concurrency In Ada
Alan Burns and Andy Wellings
Cambridge University Press, 1995 (ISBN 0-521-41471-7)
(Concurrent Programming and Real-Time Systems)

The ultimate Ada concurrency book (Burns' "Concurrent Programming In Ada") has a successor for Ada95. Written by acknowledged real-time experts, it covers the tasking model in great depth, including all the existing and new capabilities as well as the Systems Programming Annex, the Real-Time Systems Annex, and the Distributed Systems Annex. Also included are an introduction to concurrent programming and an examination of the interaction of the tasking facilities with those for object-oriented programming. More than just a detailed language examination, the book offers many examples of usage and analysis of feature interaction that only these two authors could provide. Highly recommended for introductory and advanced courses in concurrent and real-time programming with Ada. (P.R.)


Software Construction and Data Structures with Ada 95
Michael B. Feldman
Addison Wesley, 1996 (ISBN 0-201-88795-9)
(CS2/data structures)

As a book about data structures, this well-written, teachable book assumes a base knowledge of Ada, although a quick review of the basics is included.

Ada 95 features are incorporated smoothly into the discussion and the coded examples (which are available from the author). The book strikes a nice balance between theoretical issues and practice with a wealth of examples and much attention to detail, including a nice discussion on how to time a program. The extensive material coverage includes standard CS2 topics like "big O" analysis, linked lists, queues and stacks, graphs, trees, hash methods, and sorting, but the reader is allowed to investigate topics beyond the basics through additional topics like strings, vectors, tables, file I/O, sets, priority queues, AVL trees, and B-Trees, and several complete and illustrative examples, including an employee database, an airline passenger list, an RPN calculator, a discrete simulation, and even a simple window manager.

By introducing generic units relatively early (chapter 5), the text can focus on reusability and sound software engineering solutions to a wide variety of data structures problems, but never neglects the underlying analysis. As a capstone to the development of several generic data structures, chapter 14 covers generic sorting according to a wide variety of methods each with its own data structure nuances. The final chapter introduces concurrency.

The nearly 200 programs and packages have all been compiled and tested, and are available in electronic form from the author, the Addison Wesley home page, and the usual Ada archives. (S.K.)

Prof. Feldman has made available online chapter 15, Introduction to Concurrent Programming,
URL http://www.seas.gwu.edu/faculty/mfeldman/cs2-book/chap15.html


Design of Dependable Ada Software
G. Motet, A. Marpinard, J.C. Geffroy
Prentice Hall, 1996 (ISBN 0-13-204967-8)
(Software Engineering)

After participating in two European projects with major European aircraft manufacturers and suppliers, the authors wrote a book dealing with the development of dependable Ada software. This book gives advice on optimal use of Ada to design dependable software; it is not a presentation of the language.

Note: A review was published by "Software testing verification & reliability", Vol. 6, No 2, June 1996.


Méthodes de génie logiciel avec Ada 95 (In French)
(Software Engineering Methods with Ada 95)
Jean-Pierre Rosen
Paris, InterEditions, 1995 (ISBN 2-7296-0569-X)
(Software Engineering)

This is a very interesting book written by a long-standing expert in Ada and software engineering. Various methodologies are compared (Booch, HOOD, Schlaer-Mellor, etc.), all in the context of Ada 95 but not limited to language-specific discussions. Enough Ada 95 fundamentals are taught that it should not be necessary to know Ada 95 before reading the book, but this is not a book for people without some programming background.

Recommended for classes taught in French and for individuals with a good reading knowledge of French. The author is developing an English translation, which I await enthusiastically. (M.B.F.)


Object-Oriented Software in Ada 95
Michael A. Smith
International Thomson Computer Press, 1996 (ISBN 1-85032-185-X)
(Object-Oriented Programming for Advanced Undergraduates)

This book begins by providing an introduction to problem solving using a Fusion-based object-oriented design methodology, in addition to examining the basic constructs in the Ada 95 language. The book then moves on to discuss the object-oriented features of the language, using numerous examples to illustrate the ideas of encapsulation, inheritance, and polymorphism. The book's capstone is a detailed case study of the design and implementation of a textual user interface (TUI) using object-oriented design methodology. This is a nice, understandable, straightforward book on OOP with Ada 95, quite suitable for self-study or an advanced undergraduate course. The brief survey of Ada 95 at the beginning should be sufficient for readers with programming experience. The several dozen source code files are available on the Internet. (M.B.F.)


Group 3: General Texts Covering All of Ada 95

Ada 95 Rationale: The Language, The Standard Libraries
John Barnes (ed.)
Springer-Verlag, 1997 (ISBN 3-540-63143-7)

The Ada 95 Rationale is the companion to the reference manual and language standard; it introduces Ada 95 and its attractive new features and explains the rationale behind them. It should be studied in parallel with the Ada 95 Reference Manual.

It comes in four parts. The introductory part is a general discussion of the scope and objectives of Ada 95 and its major technical features. The second part contains a more detailed step by step account of the core language. The third part consists of several annexes addressing the predefined environment and specialized application areas. Finally, the three appendices of the fourth part are devoted to the upward compatibility with Ada 83, a few changes since the drafts of the standard were made public, and a summary of requirements.


Programming In Ada 95, first edition
John Barnes
Addison-Wesley, 1995 (ISBN 0-201-87700-7)

This new book by John Barnes continues a tradition of easy readability that belies the depth of understanding required to make a complex subject accessible. Though a new book for a new Ada, the style and humor from the earlier book remain. The new Ada standard is covered as a language in its own right, with few references to its predecessor beyond a summary of language differences in each chapter. The core facilities are covered extensively, with emphasis on rationale and the "programming in the large" issues of abstraction, OOP, tasking and exceptions. Of particular value is the chapter entitled Object Oriented Techniques, which explores the application of the OOP, tasking and generic unit facilities explained earlier in the book. Each chapter contains coding exercises for further study, with fullly worked-out answers in the back. The many who appreciated the earlier book will likewise enjoy this, the new classic on Ada95. Highly recommended for readers with programming experience. (P.R.)


Ada as a Second Language (2nd Edition)
Norman Cohen
McGraw Hill, 1996 (ISBN 0-07-011607-5)

This is more like a new book than like a new edition. The first edition of this book was a excellent reference to Ada(83), well organized and filled with excellent examples of realistic code sequences. It was the perfect reference to the language for those with substantial programming experience in another programming language. One of the more important features of the first edition is a well constructed index, which becomes the major passageway into the book as it grows old and worn.

That was the first edition, the second edition builds upon the excellent organization that made the first edition an excellent reference and adds material on the new features in Ada(95). To be more precise, the new material is not added, it is integrated into a seamless reference to Ada(95). The book is composed into twenty well focused chapters and five appendices, including an appendix on the special needs annexes. Each chapter concludes with two sections, one on differences between Ada(83) and Ada(95), and a very brief chapter summary. Isolating the discussion of '83 versus '95 differences to a single section in each chapter has kept the rest of the presentation in each chapter clean and to the point.

As an example of the quality in this book, consider Chapter Twelve, Classwide Programming. This is the chapter that describes Ada's object oriented programming support. Again the word "seamless" comes to mind. Unless you know ahead of time what are the new features in the language and what are the old features, you could not tell from the presentation. Polymorphism, type extension, dispatching are presented in a clear direct way, with excellent sample pieces of code. I was particularly impressed by the clean presentation of Ada.Finalization, and the realistic easy to follow sample code for the Initialize, Finalize, and Adjust procedures.

In conclusion, "Ada as a Second Language, is the best non-language lawyer reference to Ada(95), even for those whose first language is Ada(83). (J.B.)


Ada 95 for C and C++ Programmers
Simon K. Johnston
Addison Wesley, 1997 (ISBN 0-201-40363-3)

Simon Johnston's work makes an important contribution to the growing collection of Ada 95 texts for specific audiences. Johnston's target readers are the many programmers with experience in the C and C++ languages. Johnston's perspective is that of an active software developer fluent in all these languages; his goal is to show readers how Ada 95 helps them to do what they already know how to do in C and C++.

Johnston has shown considerable bravery by putting early versions of this text on the World Wide Web. He has revealed his ideas to the eyes of many thousands of critical readers, and this courageous approach has benefited both readers and author. The result is a very polished piece of work.

Three features of Johnston's book are especially useful. First, his prose and code are cogent and clear. Second, throughout the book the author develops and follows through one major case study, introducing Ada 95 capabilities through refinement of the design and alternative strategies. Finally, Johnston introduces and carefully explains the richness of the standard libraries, presenting these in a systematic fashion without merely paraphrasing the Reference Manual.

This book is bundled with a CDROM that includes the book's program distribution as well as the Aonix ObjectAda Special Edition development system. For the C or C++ programmer, Johnston's text, aided by this or another of the nice Ada 95 development systems, will go far in making the Ada 95 experience a pleasant and rewarding one. (M.B.F.)


Rendezvous with Ada 95
David J. Naiditch
John Wiley and Sons, 1995 (ISBN 0-471-01276-9)

This book is a revision of Naiditch's earlier "quick introduction" to Ada for experienced programmers. The second edition is no longer "quick" (it is nearly 150 pages longer) but is the best integrated introduction to Ada 95 to appear thus far. One wishes only that the author had provided more complete, compilable examples instead of the fragments so typical of Ada texts. (M.B.F.)


Ada 95 Reference Manual: Language and Standard Libraries,
International Standard ISO/IEC 8652:1995(E).

S. Tucker Taft, Robert A. Duff (eds)
Springer-Verlag, 1997 (ISBN 3-540-63144-5)

The Ada 95 Reference Manual completely documents the Ada 95 standard and thus is an indispensable working companion for anybody using Ada professionally or learning the language systematically.


Ada 95: The Lovelace Tutorial

This book, based on a very successful world-wide web tutorial, introduces the basic elements of Ada 95 to those who already know another programming language (e.g. Pascal, C, C++, Fortran, or Basic). It is divided into a large number of small sections (most of which end in a question) to improve understanding.

As chair of the SIGAda Education Working Group, and a denizen of the Internet newsgroups, I am often asked to give references for "Ada textbooks." This list responds to these many queries for Ada 83.

The textbooks in the Group 1 are written especially for students without programming experience, who are learning Ada as their first language. Most of these can also cover at least part of a typical CS2-level course. The books in Group 2 use Ada as their language of discourse but are "subject-oriented:" data structures, file structures, compilers, comparative languages. The remaining books in Group 3 are either "Ada books" focusing on the language features or more general books that use Ada, at least in part, but do not fit obviously into a standard curriculum "pigeonhole."

I invite you to add to the list. Please write your annotated entry in the form I have used here and write or e-mail it to me, mfeldman@seas.gwu.edu . I will include it in my next version and credit you as a co-compiler of the list.

Disclaimers: I wrote two of the texts listed here; I hope the annotations are impartial enough. And any annotated bibliography is selective and opinionated. Your mileage may vary.


Group 1: Books Suitable for a First Course in Programming with Ada 83

Bover, D.C.C., K.J. Maciunas, and M.J. Oudshoorn.
Ada: A First Course in Programming and Software Engineering.
Addison-Wesley, 1992. ISBN 0-201-50992-X
This work is, to our knowledge, the first Ada book to emerge from Australia, from a group of authors with much collective experience in teaching Ada to first-year students. A number of interesting examples are presented, for example, an Othello game. The book is full of gentle humor, a definite advantage in a world of dry and serious texts. In the book's favor is the large number of complete programs. On the other hand, it is rather "European" in its terseness; American teachers may miss the pedagogical apparatus and "hand-holding" typically found in today's CS1 books. Generic units are hardly mentioned.

Culwin, F.
Ada: a Developmental Approach.
Prentice-Hall, 1992.
This work introduces Ada along with a good first-year approach to software development methodology. Much attention is paid to program design, documentation, and testing. Enough material is present in data structures and algorithm analysis is present to carry a CS2 course. A drawback of the book is that the first third is quite "Pascal-like" in its presentation order: procedures, including nested ones, are presented rather early, and packages are deferred until nearly the middle of the book. This is certainly not a fatal flaw, but it will frustrate teachers wishing a more package-oriented presentation. The programs and solutions are apparently available from the author.

Dale, N., D. Weems, and J. McCormick.
Programming and Problem Solving with Ada.
D. C. Heath, 1994. ISBN 0-669-29360-1
This book is inspired by Dale and Weems' very successful Introduction to Pascal and Structured Design, but it is not simply an Ada version. Ada's more advanced capabilities such as exceptions, packages and generic units are included in this text. In addition, more than half of the material is completely new, and the order of the topics is signficantly different. It also has more of a software engineering focus than the Pascal version. The only Ada topics not included in this text are tasks and access types. Procedures and packages are introduced early. Each chapter includes case studies, testing and debugging hints and excellent non-programming exercises and programming problems. The text comes with a program disk containing all the programs given in the book. In addition, a validated Meridian Ada compiler with complete documentation is available at low cost to students using this book. (S. P. L.)

DeLillo, N. J.
A First Course in Computer Science with Ada.
Irwin, 1993. (ISBN 0-256-12538-4)
This book is a first in the Ada literature: a version comes with an Ada compiler, the AETech-IntegrAda version of Janus Ada. Author, publisher, and software supplier are to be commended for their courage in this. The book itself covers all the usual CS1 topics. In my opinion, the order of presentation is a bit too Pascal-like, with functions and procedures introduced in Chapter 5 (of 15) and no sign of packages (other than Text_IO) until Chapter 10. Unconstrained arrays and generics are, however, done nicely for this level, and Chapter 13 is entirely devoted to a single nontrivial case study, a statistical package. I wish there were more complete programs in the early chapters, to put the (otherwise good) discussion of control and data structures in better context.

Feldman, M.B., and E.B. Koffman.
Ada: Problem Solving and Program Design.
Addison-Wesley, 1992. ISBN 0-201-53364-2
This work combines the successful material from Koffman's CS1 pedagogy with a software-engineering-oriented Ada presentation order. Packages are introduced early and emphasized heavily; chapters on abstract data types, unconstrained arrays, generics, recursion, and dynamic data structures appear later. The last five chapters, combined with some language-independent algorithm theory, can serve as the basis of a CS2 course. A diskette with all the fully-worked packages and examples (about 180) is included; the instructor's manual contains a diskette with project solutions. A second edition, with Ada 95 as the language, is in preparation and due out at the beginning of 1996.

Savitch, W.J. and C.G. Petersen.
Ada: an Introduction to the Art and Science of Programming.
Benjamin/Cummings, 1992. ISBN 0-8053-7070-6
This is a straightforward adaptation of the well-known Savitch Pascal books. Ada is introduced in a Pascal-like order, with subtypes and packages introduced halfway through the book. This is purely a CS1 book. The final chapter covers dynamic data structures. There is minimal coverage of unconstrained array types; generics are introduced at the halfway point to explain Text_IO, then continued only in the final chapter. The authors intended this book to provide a painless transition to Ada for teachers of Pascal; one wishes they had taken advantage of the chance to show some of the interesting Ada concepts as well. Program examples from the text are available on disk, but only as part of the instructor's manual; a solutions disk is available for a fee from the authors.

Skansholm, J.
Ada from the Beginning. (2nd ed.)
Addison Wesley, 1994. ISBN 0-201-62448-6
This book was one of the first to use Ada with CS1-style pedagogy. There are excellent sections on the idiosyncracies of interactive I/O (a problem in all languages), and a sufficient number of fully-worked examples to satisfy students. Generics, linked lists and recursion are covered at the end; there is no tasking coverage, but one would not expect this at CS1-level. A very interesting addition is the new Chapter 14, in which OOP in both Ada 83 and Ada 95 is discussed. This is an especially lucid explanation of OOP in Ada, and makes a real contribution because it doesn't just discuss tagged types as a "feature" of Ada 95, but shows very nicely what is possible in Ada 83 (instead of just what is _not_ possible), and shows how Ada 95 adds functionality.

Smith, J. F., and T. S. Frank
Introduction to Programming Concepts and Methods with Ada
McGraw-Hill, Inc., 1994 ISBN 0-07-911725-2
This is a well written and easy to use text. The book takes a spiraled approach to CS 1. The authors do an excellent job integrating Ada into the book. They take a very direct approach, especially with an early introduction to the package concept and the traditional Text_IO package. Faculty who have taught CS 1 with Pascal should like this book. Instead of making a big fanfare about Ada features, they simply introduce them as good support for software development concepts. The authors have carefully chosen the Ada topics they decided to cover in this book in order to strike a balance between staying true to the CS 1 course while presenting enough of the programming language. If you teach CS 1 you might at least want to get a copy of this text just to look at two chapters, Chapter 7 and Chapter 14. Seven covers program correctness and run-time event (exception handling) and fourteen is a beautiful presentation and example of generic packaging. Both presentations are done in an appropriate manner for CS 1. (J. B.)

Volper, D., and M. Katz.
Introduction to Programming Using Ada.
Prentice-Hall, 1990. ISBN 0-13-493529-2
This book uses a heavily "spiraled" approach to Ada, and is designed for a 2-semester course, covering nearly all of Ada eventually. There are lots of fully-coded examples, and good pedagogical sections on testing, coding style, etc. If you like spiraling, you'll like this. The down side is that you can't find all you need on a given subject in one place. It's at the other end of the scale from the "Ada books" that follow the Ada Language Reference Manual (LRM) order.


Group 2: Other Ada 83 Books Intended for Undergraduate Courses

Ben-Ari, M.
Principles of Concurrent and Distributed Programming.
Prentice-Hall 1990. ISBN 0-13-711821-X
(OS/concurrency)
In my opinion, this is the best introduction to concurrency on the market. Ada notation is used for everything, but the focus is on concurrency and not on Ada constructs per se. I liked the CoPascal notation of the first edition better, but this book is still great. A software disk is promised in the preface; I had to work quite hard to get it from the publisher, which finally had to express-ship it from England. The software comes with a tiny Ada-ish interpreter, complete with Pascal source code, adapted from Wirth's Pascal/S via CoPascal. There are also some real Ada programs, most of which I've tested and found correct and portable.

Feldman, M.B.
Data Structures with Ada.
Addison Wesley, 1993. ISBN 0-201-52673-5
(CS2/data structures)
This book is a reasonable approximation to a modern CS2 book: "big O" analysis, linked lists, queues and stacks, graphs, trees, hash methods, and sorting, are all covered. The Ada is a bit old-fashioned, especially the lack of generics; the book was published before compilers could handle generics. The packages and other programs are available free from the author. The book has been heavily revised; the Ada 95-based second edition should appear early in 1996 from Addison-Wesley.

Fischer, C., and R. LeBlanc.
Crafting a Compiler.
Benjamin Cummings, 1988. ISBN 0-8053-3201-4
(compilers)
This book uses Ada as its language of discourse and Ada/CS, a usefully large Ada subset, as the language being compiled. If you can get the "plain Pascal" tool software by ftp from the authors, you'll have a good translator-writing toolset. Skip the Turbo Pascal diskette version, which is missing too many pieces to be useful. I've used the book since it came out with both undergrad and graduate compiler courses; it embodies a good blend of theory and "how it's really done" coding. Students like it. The authors have recently published a second version, which uses C as its coding language but retains Ada/CS as the language being compiled.

Hillam, B.
Introduction to Abstract Data Types Using Ada.
Prentice-Hall, 1994. ISBN 0-13-045949-6
(data structures)
This is a very readable treatment of data structures presented using Ada that makes good use of Ada features such as generics. It contain many complete programs and packages. Unfortunately, obvious syntax errors make it apparent that not all examples have been compiled. The level of presentation is somewhere between an elementary, CS 2, data structures course and an advanced, CS 7, course. A subset of first eleven chapters provide the appropriate topics for a CS 2 course, but not the pedagogy necessary for a course at that level. (D. J.)

Lomuto, N.
Problem-Solving Methods with Examples in Ada.
Prentice-Hall, 1987.
(algorithms)
Inspired by Polya's classic How to Solve It, this book can make a nice addition to an Ada-oriented algorithms course. It makes too many assumptions about students' programming background to use as a CS1 book, and doesn't teach enough Ada to be an "Ada book." But it makes nice reading for students sophisticated enough to handle it. I'd classify it as similar to Bentley's Programming Pearls.

Miller, N.E. and C.G. Petersen.
File Structures with Ada.
Benjamin/Cummings, 1990. ISBN 0-8053-0440-1
(file structures)
Designed for a straightforward ACM-curriculum file structures course, this book succeeds at what it does. There are good discussions of ISAM and B-tree organizations. The software can be purchased a low cost from the authors; it seems to approximate in Ada all those C-based file packages advertised in programmer-oriented trade publications.

Schneider, G.M., and S.C. Bruell.
Concepts in Data Structures and Software Development
(with Ada Supplement by P. Texel).

West, 1991.
(CS2/data structures)
This work is not, strictly speaking, an Ada book; rather, it is a solid, language-independent approach to modern CS2. The language of discourse in the book is a Pascal-like ADT language rather like Modula-2 in style; some examples are coded in legal Pascal. The Ada supplement makes it usable in an Ada-based course, but the supplement is rather too terse (100 pages of large type) for my taste, and insufficiently well keyed to the book chapters. The supplement's effectiveness would be greatly enhanced by full translations to Ada of a large number of the book's examples.

Sebesta, R.W.
Concepts of Programming Languages (2nd ed.).
Benjamin Cummings, 1993. ISBN 0-8053-7132-X
(comparative languages)
If you've been around for a while, you might remember the late Mark Elson's 1975 book by the same title. This is similar: a concept-by- concept presentation, with -- in each chapter -- examples taken from several languages. I include this work in an "Ada list" because I like its nice, impartial coverage of Ada. I especially like the chapters on abstraction and exception handling. The book covers -- comparatively, of course -- most of the lanuages you'd like to see, including C, C++, Lisp, Smalltalk, etc., with nice historical chapters as well. The book is readable; my students like it. Our undergraduate and graduate courses both use it as a base text.

Stubbs, D.F., and N.W. Webre.
Data Structures with Abstract Data Types and Ada.
PWS-Kent, 1993. ISBN 0-534-14448-9
(advanced data structures)
This work updates and adapts to Ada the material in the authors' successful data structures texts using Pascal and Modula-2. It is good for a "heavy" CS2, i.e., one on the theoretical side, or a "light" CS7, i.e. it is not as theory-oriented as the Weiss work below. More Ada, especially regarding advanced types, is taught here than in Weiss. Especially interesting about all the books from these authors is that they have matched their "big O" performance prediction with tables and graphs showing actual performance measurements.

Weiss, M.A.
Data Structures and Algorithms in Ada.
Benjamin/Cummings, 1993. ISBN 0-8053-9055-3
I think this book reaches its intended market -- data structures courses (CS7) -- rather well with Ada. There's a good mixture of theory and practice (ADT design, for example), and coverage of new topics like amortized algorithm analysis and splay trees. A book at this level should not pay too much attention to teaching a language; rather it should make good use of its language of discourse. The Ada version does not attempt to teach either the language or Ada-style software engineering, but shows good understanding of the language, uses generic packages quite well and focuses on the theory of algorithms, as a book at this level should. This is the first, and so far the only, text in Ada for this course.


Group 3: A Selection of Other Ada 83-Related Books

Barnes, J. G. P.
Programming in Ada. (4th edition)
Addison-Wesley, 1994. ISBN 0-201-62407-9
Barnes' work has been one of the most popular "Ada books." Some students find it hard to see how the pieces fit together from Barnes' often fragmentary examples; it is difficult to find complete, fully-worked out, compilable programs. On the other hand, this book has been a real best-seller, so Barnes clearly is doing something right. The fourth edition has a 100-page summary of Ada 95, and a fully-integrated Ada 95 fifth edition is in production for Fall 1995 release. Also, the third (Ada 83) edition is still in print, with an Ada 83 reference manual included.

Booch, G.
Software Components with Ada.
Benjamin Cummings, 1987. ISBN 0-8053-0610-2
This work is an encyclopedic presentation of data structure packages from Booch's OOD point of view. It is great for those who love taxonomies. It's not for the faint-hearted, because the volume of material can be overwhelming. It could serve as a text for an advanced data structures course, but it's thin in "big O" analysis and other algorithm-theory matters. The book is keyed to the (purchasable) Booch Components.

Booch, G. and D. Bryan, with C. Petersen
Software Engineering with Ada. (3rd edition)
Benjamin/Cummings 1994. ISBN 0-8053-0613-7
Another of the classical "Ada books." Introduces Booch's OOD ideas. Not for use to introduce Ada to novices, in my opinion; there are some nice fully-worked case studies but they begin too far into the book, after long sections on design, philosophy, and language elements. The earlier chapters contain too much fragmentary code, a common flaw in books that follow the LRM order. The third edition contains an appendix describing Ada 9X.

Bryan, D.L., and G.O. Mendal.
Exploring Ada, Volumes 1.and 2.
Prentice-Hall, 1990 and 1992 respectively. ISBN 0-13-295684 (vol. 1); ISBN 0-13-297227-1 (vol. 2)
This is an excellent study of some of the interesting nooks and crannies of Ada; it sometimes gets tricky and "language-lawyerly." Volume 2 takes up tasking, generics, exceptions, derived types, scope and visibility; Volume 1 covers everything else. The programs are short and narrowly focused on specific language issues. If you like Bryan's "Dear Ada" column in Ada Letters, you'll like this book. It is certainly not a book for beginners, but great fun for those who know Ada already and wish to explore.

Burns, A., and G. Davies.
Concurrent Programming.
Addison-Wesley, 1993, ISBN 0-201-54417-2
Solid book covering all aspects of writing concurrent software. Uses a version of Pascal called FC-Pascal (available for free through the Internet). The FC means "Functionally Concurrent". It has constructs that are similar to Ada 9X, and this is by no accident -- the authors frequently point out that the implementations in FC-Pascal are taken from Ada 9X's Tasks and Protected Types. Covers lots of low-level problems by gradually building up from simple examples. Highly recommended for a Concurrent Programming class. Exercises and Further readings are provided at the end of each chapter. (D.W.)

Burns, A. and A. Wellings.
Real Time Systems and their Programming Languages
Addison-Wesley 1990. (ISBN 0-201-17529-0)
This is an excellent and unique book. Basic concepts and terminology are explained before moving on to explain the major aspects of real time design. "Real world" examples are presented in Ada, Modula-2 and occam 2, though Ada is clearly the authors' language of choice and gets the most coverage. Topics covered include reliability and fault tolerance, concurrency, synchronisation, scheduling, message passing, atomic transactions, resource control, distributed systems and low-level device control. Efficiency is not neglected, and Ada support here is particularly strong with detail on the CIFO package. Several case studies are also presented. The only failing of the book is that it needs updating to cover Ada 9x and its real-time annex, Modula-3 etc. However, the basic concepts that the authors convey so clearly are independent of implementation language. (M. L.)

Cohen, N.
Ada as a Second Language.
McGraw Hill, 1986. ISBN 0-07-011589-3
This book is a quite comprehensive exploration of Ada which follows the LRM in its presentation order. My graduate students like it because it is more detailed and complete than alternative texts. It's an excellent book for students who know their languages and want to study all of Ada. There are good discussions of "why's and wherefore's" and many long, fully-worked examples. An anxiously-awaited 2nd edition covering Ada 95 is in the pipeline.

Gauthier, M.
Ada: Un Apprentissage (in French).
Dunod, 1989.
Ada: a Professional Course (in English).
Macmillan Computer Science Series, 1993. ISBN 0-333-58001-X.
I found this an especially interesting, almost philosophical approach to Ada. The first section presents Ada in the context of more general laguage principles: types, genericity, reusability. The second section introduces testing and documentation concerns, as well as tasking; the third considers generics and variant records in the more general context of polymorphism. For mature Ada students in the French-speaking world, and others who can follow technical French, this book can serve as a different slant on the conventional presentations of the language. The more recent English edition is a contribution to the Ada literature in English, because of its getting behind the language itself into the more general language-design principles.

Gehani, N.
Ada: an Advanced Introduction (2nd edition).
Prentice-Hall, 1989. ISBN 0-13-004334-6
I've always liked Gehani's literate writing style; he knows his languages and treats Ada in an interesting, mature, and balanced fashion. This book comes with a diskette sealed in the back of the book, which is advantageous because the book has numerous nontrivial, fully- worked examples.

Gehani, N.
Ada: Concurrent Programming (2nd edition).
Silicon Press, 1991. ISBN 0-929306-08-2
This is a less formal, more Ada-oriented presentation of concurrency than the Ben-Ari work. I use both books in my concurrency course; its real strength is the large number of nontrivial, fully worked examples. Gehani offers a nice critique of the tasking model from the point of view of an OS person. The preface promises the availability of a software disk from the publisher.

Nyberg, K. (editor)
The Annotated Ada Reference Manual. (3rd edition)
Grebyn Corporation, 1993.
This is the definitive work on Ada 83 legalities, because it presents not only the full text of the LRM but also the official Ada Interpretations as prepared by the Ada Rapporteur Group of Working Group 9 of the International Organization for Standardization (ISO) and approved by that organization. These commentaries, interleaved with the LRM text, are promulgated by the Ada Joint Program Office, the American National Standards Institute (ANSI) agent for Ada, in the Ada Compiler Validation Suite (ACVC). They are thus binding upon compiler developers. I recommend this book as an essential volume in the library of every serious Ada enthusiast.

Watt, D.A., B.A. Wichmann, and W. Findlay.
Ada Language and Methodology.
Prentice-Hall, 1987. ISBN 0-13-004078-9
This work presents some interesting programming projects, and the coverage of design and testing--at the level of a first-year student--is quite good. The first third of the book concentrates heavily on classical control and data structures, leaving subprograms until Chapter 12, and exceptions and packages until the "programming in the large" material in the second third. CS2 teachers will find too little concentration on algorithm analysis. On the other hand, tasking and machine-dependent programming are covered. Like the Shumate work, this book would make a suitable introduction to Ada for students with a semester or so of programming experience; it "jumps in" too quickly to satisfy the needs of neophytes and is not well-tailored to CS1 or CS2 needs.
