C++ Templates (Chinese Edition)

This book is a systematic guide to C++ template programming, using three threads—"basic concepts, common techniques, and practical examples"—to help readers build a solid foundation in templates. It has 22 chapters in four parts. Part One introduces template fundamentals in tutorial style: writing function and class templates, template argument deduction, template parameters, default template arguments, and overloading. Part Two delves into the language details of templates, discussing rules that are easily overlooked, such as name lookup, instantiation, specialization and partial specialization, inheritance in templates, and dependent names. Part Three introduces the basic design techniques templates enable, such as traits, policy classes, and the CRTP. Part Four applies these techniques to real scenarios, covering metaprogramming and expression templates. Appendices A and B compile material on the One Definition Rule and overload resolution, respectively, for handy desk reference. The authors, David Vandevoorde and Nicolai M. Josuttis, are both members of the C++ standards committee; the extensively commented code examples explain not only "how to write" but also "why to write it this way" and how the compiler's two-phase lookup works. The content is based on C++98/03, so it serves as a foundational reference for understanding the template compilation model; readers should note how it maps to features added in later standards.
