I found this a very interesting book with good quality solutions and associated discussion.
Over the years I have used the various editions of the 'C++ Primer' as a good source of programming techniques and as a general reference. I attempted some of the exercises and often wondered how correct and efficient the answers were. This text provides a set of answers to exercises in the 'C++ Primer' third edition by Lippman&Lajoie (there have been several reviews of this book in C Vu).
In the 'Answer Book' each chapter maps to the corresponding chapter in the 'C++ Primer'. Each exercise is presented with a sample solution, which is followed by a discussion that analyses the problem and explains the solution, e.g. design approach taken. In many cases there are appropriate quotes from the 'C++ Primer' with additional expanded discussion. There is a foreword by Lippman and Lajoie discussing the origins and aims of the text (which they reviewed before publication).
I found this a very interesting book with good quality solutions and associated discussion. If you use the 'C++ Primer' or have it as a set text for a programming course this book is well worth having as a supporting text. It enables practical experience to be gained by doing the exercises and then the answers checked against the solutions presented. For example, this would be very useful in tutorials where students would work through an exercise and then discuss their solutions and compare them with the sample. Be careful if you are setting any of the exercises as coursework though! Highly recommended!
