书籍介绍

这并非一本教你C++11新语法的入门书，而是给已掌握C++、却在新标准下屡屡踩坑的开发者准备的「避坑手册」。作者Scott Meyers没有泛泛而谈「现代C++有什么好处」，而是聚焦那些看似简单、实则暗藏陷阱的细节：花括号与圆括号初始化的微妙差异、std::move何时会帮倒忙、完美转发如何被意外截断。读者最看重的，是它把「为什么该这么做」讲透，而非罗列「该怎么做」的教条。条目之间相对独立、含金量分布均匀，避免了技术书常见的「狗尾」式注水，适合随时查阅。它适合那些写过C++98、正努力将旧代码迁移到现代标准、并渴望理解背后原理而非死记规则的工程师。

精彩摘录

"......create softerware that's correct efficient maintainable portable"
"C++98 had a single set of rules for type deduction: the one for function templates. C++11 modifies that ruleset a bit and add two more, one for auto and one for decltype. C++14 then extends the usage contexts in which auto and decltype may be employed."
"When users of a complex system are ignorant of how it works, yet happy with what it does, that says a lot about the design of the system. By this measure, template type deduction in C++ is a tremendous success."
"The ability to declare references to arrays enables creation of a template that deduces the number of elements that an array contains."
"The only real difference between auto and template type deduction is that auto assumes that a braced initializer represents a std::initializer_list, but the template type deduction doesn't."
"In C++11, perhaps the primary use for decltype is declaring function templates where the function's return type depends on its parameter types."
"The use of "decltype(auto)" is not limited to function return type. I can also be convenient for declaring variables when you want to apply the decltype type deduction rules to the initializing expression."
"Employing pass-by-value for objects of an unknown type generally risks the performance hit of unnecessary copying, the behavioral problems of object slicing, and ..."
