内容简介
所有的C++程序员都必读的书少之又少，而本书就是其中的一本。C++的标准模板库（STL）是革命性的，但是要想学会用好STL却充满了挑战性。中国台湾技术作家侯捷先生曾经把STL的学习过程比喻为三个境界：第一境界：熟用STL。第二境界：了解泛型技术的内涵与STL的学理乃至实作。第三境界：扩充STL。本书无疑是你达到第二境界的最佳读本。在本书中，C++技术权威Scott Meyers揭示了专家总结的一些关键规则，包括他们总是采用的做法以及总是避免的做法。这些规则可以发挥STL的最大效用。有些书只是描述STL中有些什么内容，而本书则讲述如何使用STL。本书共有50条指导原则，在讲述每一条指导原则时，Scott Meyers都提供了透彻的分析和深刻的实例，所以读者不仅可以学到要做什么，而且还能够知道什么时候该这样做，以及为什么要这样做。如同Meyers的其他著作一样，本书充满了从实践中总结出来的智慧。清晰、简明、透彻的风格使本书成为每一位STL程序员的案头必备。本书特色·关于选择容器的建议，涉及的容器有：标准STL容器（例如vector和list）、非标准的STL容器（例如hash_set和hash_map），以及非STL容器（例如bitset）。·一些提高效率的技术，通过它们可以最大程度地提高STL（以及使用STL的程序）的效率。·深入到迭代器、函数对象和分配子（allocator）的行为，也包括程序员总是应该避免的做法。·对于那些同名的算法和成员函数，如find，根据它们行为方式上的微妙差异，本书给出了一些指导原则，以保证它们能被正确地使用。·讨论了潜在的移植性问题，包括避免这些移植性问题的各种简单途径。
