"C++ Standard Library 第二版,基于C++11标准的官方C++标准库,涵盖了C++11的新特性,如STL(Standard Template Library),Lambda表达式,函数对象等内容。" 《C++ Standard Library》第二版是Nicolai M. Josuttis撰写的一本关于C++标准库的教程和参考书,专门针对C++11标准进行了更新。此版本深入探讨了C++11引入的新特性,使读者能够充分利用现代C++的功能来提高编程效率和代码质量。 C++ Standard Library(STL)是C++编程中不可或缺的一部分,它包含了一系列的模板类和函数对象,如容器(如vector、list、map等)、迭代器、算法和函数对象。STL的设计理念是提供一种通用、高效且可重用的编程接口,使得开发者能够处理常见的数据结构和算法问题。在C++11中,STL得到了进一步增强,例如增加了更灵活的容器如unordered_map和unordered_set,以及对范围基础的for循环的支持。 Lambda表达式是C++11中的一个重大创新,它允许在程序中定义匿名函数,简化了函数对象的创建和使用,特别是对于短小的、临时使用的函数。Lambda表达式可以捕获外部变量,支持右值引用,并且可以直接用于函数对象和算法,如std::sort或std::transform,极大地提高了代码的简洁性和可读性。 函数对象,也称为仿函数(functors),是C++中实现函数行为的对象。在C++11之前,它们通常是通过派生自std::unary_function或std::binary_function等基类来定义的。C++11引入了函数对象的改进,比如lambda表达式,使得定义和使用函数对象更加直观。此外,C++11还提供了std::function,一个可以存储任何可调用对象(包括函数指针、成员函数指针、lambda表达式等)的类型安全容器,增强了函数对象的灵活性。 书中详细讲解了这些特性的使用方法和最佳实践,同时涵盖了C++标准库的其他重要组件,如智能指针(shared_ptr、unique_ptr等)和并发编程工具(如std::thread和std::mutex)。此外,作者还讨论了错误处理、内存管理以及如何有效利用C++11的新特性进行性能优化。 总而言之,《C++ Standard Library》第二版是C++程序员必备的参考资料,无论你是初学者还是经验丰富的开发者,都能从中受益匪浅,了解和掌握C++11及STL的最新进展,提升你的C++编程技能。

C++ Standard Library Quick Reference by Peter Van Weert, Marc Gregoire 2016 | ISBN: 1484218752 | English | 206 pages PDF+EPUB This quick reference is a condensed reference guide to the essential data structures, algorithms, and functions provided by the C++ Standard Library. More specifically, this is a compact collection of essential classes and functions, used by C++ programmers on a daily basis. The C++ Standard Library Quick Reference features core classes for strings, I/O streams, and various generic containers, as well as a comprehensive set of algorithms to manipulate them. In recent years, the C++11 and C++14 standards have added even more efficient container classes, a new powerful regular expression library, and a portable multithreading library featuring threads, mutexes, condition variables, and atomic variables. Needless to say, it is hard to know and remember all the possibilities, details, and intricacies of this vast and growing library. This handy reference guide is therefore indispensable to any C++ programmer. It offers a condensed, well-structured summary of all essential aspects of the C++ Standard Library, including all aforementioned functionality. No page-long, repetitive examples or obscure, rarely used features. Instead, everything you need to know and watch out for in practice is outlined in a compact, to-the-point style, interspersed with well-chosen, clarifying examples. The book does not explain the C++ language or syntax, but is accessible to anyone with basic C++ knowledge. Even the most experienced C++ programmer though will learn a thing or two from it and find it a useful memory-aid. What You Will Learn • The essentials that the C++ Standard Library has to offer • How to use containers to efficiently store and retrieve your data • How to use algorithms to inspect and manipulate your data • How lambda expressions allow for elegant use of algorithms • What the standard string class provides and how to use it • What functionality the library provides for file and stream-based I/O • What smart pointers are and how to use them to prevent memory leaks • How to write safe and efficient multi-threaded code using the C++11 threading libraries
