Countless programmers have used previous editions of C++ Primer to learn C++. In that time C++ has matured greatly. Over the years, the focus of the languageand of C++ programmershas grown beyond a concentration on run-time efficiency to focus on ways of making programmers more efficient. With the widespread availability of the standard library, it is possible to use and learn C++ more effectively than in the past. This revision of the C++ Primer reflects these new possiblities.

无数程序员曾使用本书的前几个版本学习 C++，在此期间 C++ 也逐渐发展成熟。这些年来，C++ 语言的发展方向以及 C++ 程序员的关注点，已经从以往注重运行时的效率，转到千方百计地提高程序员的编程效率上。随着标准库的广泛可用，我们现在能够比以往任何时候更高效地学习和使用 C++。本书这一版本充分体现了这一点。
