Book aimed at advanced C++ developers who want to hone their programming chops even further, Herb Sutter’s More Exceptional C++ book borrows the format of his earlier title, Exceptional C++, and delivers some of today’s best-available thinking on the c++ language in a handy and effective format. A compilation of the author’s own experience and research on the thornier aspects of C++, this ebook will serve as a worthy resource for making sure you get the most out of this powerful language.
The concise text of the book covers a range of challenging topics in C++ without attempting to be comprehensive. Each “item” in the ebook is presented as a question to try and solve yourself before the author presents his solution, plus additional detail as needed. For most topics of the book, Sutter ends by giving his advice on the best practices (and gotchas to avoid).
Early sections of the book concentrate on using Standard Template Library (STL) container classes, like removing items effectively, and the subtle differences between container types. Standout sections of the ebook on designing custom templates (using specialization techniques) and exception-safe classes will help you do more with your own classes. One entertaining problem here shows a number-guessing game (Mastermind) built as efficiently as possible using STL code (including expert-level use of generic functions to do much of the work).
Several problems on copy-on-write (COW) semantics for more efficient classes point out the issues surrounding code optimization. There has been a debate in the C++ community for years about whether it’s possible to design truly “exception-safe” classes. Sutter, in his books, points out the difficulty with a precise analysis of the issues surrounding exceptions and C++ constructors. Material on the finer points of inheriting classes of the ebook (including when to avoid and when to use multiple inheritance in C++) will extend your class design options. A good section of the book is the author’s explication of how to simulate COM/Java style interfaces in C++, which isn’t immediately obvious, even to experienced C++ developers.
Later sections of the ebook delve into code maintenance issues, including advice for using macros, typedefs, and namespaces. (Advice on migrating existing C++ code into namespaces will help you combine legacy code with other libraries.) A final appendix of the book shows off some benchmarks for optimizing strings using a variety of techniques.
Intelligent, provocative, and demanding, More Exceptional C++ shows why C++ continues to be a rich, complex, and challenging language. Armed with titles like this one, experienced C++ programmers can write better code and avoid pitfalls buried in the outer edges of their favorite language.
