Scott Meyers是全世界最知名的C++软件开发专家之一。他是畅销书《Effective C++》系列（Effective C++,More Effective C++,Effective STL）的作者，又是创新产品《Effective C++ CD》的设计者和作者，也是Addison-Wesley的“Effective Software Development Series"顾问编辑，以及《Software Development》杂志咨询板成员。他也为若干新公司的技术咨询板提供服务。Meyers于1993年自Brown大学获得计算机博士学位。他的网址是www,aristeia.com.
《Effective C++中文版（第3版改善程序与设计的55个具体做法）》一共组织55个准则，每一条准则描述一个编写出更好的C++的方式。每一个条款的背后都有具体范例支撑。第三版有一半以上的篇幅是崭新内容，包括讨论资源管理和模板（templates）运用的两个新章。为反映出现代设计考虑，对第二版论题做了广泛的修订，包括异常（exceptions）、设计模式（design patterns）和多线程（multithreading）。
《Effective C++中文版（第3版改善程序与设计的55个具体做法）》的重要特征包括：
·高效的 classes、functions、templates 和inheritance hierarchies（继承体系）方面的专家级指导。
·崭新的 TR1 标准程序库功能应用，以及与既有标准程序库组件的比较。
·洞察 C++和其他语言（例如Java、C#、C）之间的不同。此举有助于那些来自其他语言阵营的开发人员消化吸收 C++ 式的各种解法。
