Meyers shows you when these classes make sense and the best ways to implement them. (Even advanced developers will learn something here.) Sections on using function objects (called functors) round out the text.

Meyers shows you how to choose the correct algorithm for sorting and other functions. Other areas covered in Effective STL cover getting the most out of the 100-plus STL algorithms that are bundled with this library.

You'll also learn to avoid common pitfalls, which can result in writing code that is slow or just plain wrong. (Besides the standard built-in containers, the author also highlights recent additions to STL like B-trees, which are available as extensions from other vendors.) You'll learn the best ways to allocate, add, change, and delete items inside containers, including associative containers like maps. (Advanced developers will enjoy Meyers's in-depth explanations, while those who are in a hurry can skip ahead to the recommended tip itself.)Ī good part of this book involves using containers, like vectors and maps, which are built into STL. Each tip is demonstrated with in-depth coding samples, many of which make use of two-color printing to highlight the most important lines of code. Besides providing a list of dos and don'ts, Meyers presents a lot of background on what works and what doesn't with STL. The book is organized into 50 tips that explore different areas of the STL. STL is a hugely powerful feature of today's C++, but one with a well-earned reputation for complexity. Written for the intermediate or advanced C++ programmer, renowned C++ expert Scott Meyers provides essential techniques for getting more out of the Standard Template Library in Effective STL, a tutorial for doing more with this powerful library. Guidance for the proper use of algorithms and member functions whose names are the same (e.g., find), but whose actions differ in subtle (but important) ways.ĭiscussions of potential portability problems, including straightforward ways to avoid them. Insights into the behavior of iterators, function objects, and allocators, including things you should not do. Techniques to maximize the efficiency of the STL and the programs that use it. Each of the book’s 50 guidelines is backed by Meyers’ legendary analysis and incisive examples, so you’ll learn not only what to do, but also when to do it – and why.Īdvice on choosing among standard STL containers (like vector and list), nonstandard STL containers (like hash_set and hash_map), and non-STL containers (like bitset). In this book, best-selling author Scott Meyers ( Effective C++, and More Effective C++ ) reveals the critical rules of thumb employed by the experts – the things they almost always do or almost always avoid doing – to get the most out of the library.

– Thomas Becker, Senior Software Engineer, Zephyr Associates, Inc., and columnist, C/C++ Users JournalĬ++’s Standard Template Library is revolutionary, but learning to use it well has always been a challenge. “There are very few books which all C++ programmers must have. – Herb Sutter, independent consultant and secretary of the ISO/ANSI C++ standards committee “This is Effective C++ volume three – it’s really that good.”
