The latest edition of the definitive guide to the Ada language covers the full details of the core language Ada 2012 as updated by the 2016 ISO Corrigendum and introduces the key new features in Ada 2022. The book is in four parts. It begins by introducing the fundamental concepts for newcomers, before moving onto algorithmic aspects and then structural features such as OOP and multitasking. The fourth part gives details of the standard library and interaction with the external environment. Six complete executable programs illustrate the core features of the language in action. The book concludes with an appendix focussing on the new features in Ada 2022. These new features aid program proof and the efficient use of multicore architectures.

‘As he has done similarly before, in this special edition of his classic ‘Programming in Ada’ text, John Barnes introduces the reader to a new version of Ada, namely ‘Ada 2022’, with both rigour and vigor. John is unique in his ability to explain new Ada features in a way that makes them both immediately understandable and immediately usable, because of the helpful context and witty examples he provides. As a member of the group that maintains the Ada language standard, John knows the ins and outs of why the features ended up as they did, but he seems to always be the best at rising above the minutiae the typical language design team member worries about, to see the big picture and how the new feature fits into the overall language, and how it can benefit the programmers building critical applications in Ada.’

S. Tucker Taft - Director of Language Research, Ada Core

‘This new revision of ‘Programming In Ada’ will ensure that it remains the essential companion of any Ada practitioner. It is a useful guide that brings to life the more formal language of the ‘Ada Reference Manual’. As one has come to expect of John’s work, it includes many practical examples which will no doubt go on to be used as templates for much real code.’

Jeff Cousins - CEng FIET, Member and past Chair of the Ada Rapporteur Group

‘With the introduction of the Ada 2022 revision of the Ada programming language, we have a new collection of language features with definitions that need explaining, interactions with other features that need clarifying, and potential applications that need illustrating. Fortunately, this latest edition of John Barnes' excellent book admirably meets this need in a way that will be useful for both Ada beginners and experienced Ada users.’

Steve Baird - Chair of the Ada Rapporteur Group

‘This latest book on Ada by John Barnes continues a tradition of easy readability and subtle humor that belies the depth of understanding required to make a complex subject accessible. The details of semantics and syntax remain well balanced with rationale and design intent as the new book covers the most recent updates to Ada 2012. As each part of Ada 2012 is covered, relevant Ada 2022 material is introduced, with references to an annex dedicated to Ada 2022. Thus the reader can focus on the language version currently most in use, yet also learn the exciting capabilities coming in Ada 2022. When teaching Ada courses I've invariably recommended John's latest book because each represents the best combination of technical detail and examples of how the language can be elegantly applied. I'm sure I will recommend this latest book as well.’
