如果你已经知道如何用 C++ 实现简单的面向对象、元编程（模板编程），那我认为 Primer 是可看可不看的。Primer 里当然不只有这点知识，但 Primer 有些太专注于 C++ 及标准库本身，目的性不强。如果你是个慢性子，现在也不着急要做出什么东西，那花上两三个月慢慢跟着 Primer 走也不错。如果你不想这样，那不看 Primer 直接选定一个方向也没问题。

我给出这种观点的理由是 C++ 的语法表达能力太强，编程风格太自由，导致没有点习惯来约束的话容易不知道用哪些特性来写代码。而 C++ 的主要应用领域（比如图形学、数值计算、数据库内核、网络、嵌入式）各有各的编程习惯，如果你已经有意向学习某个领域，最好去找个相关的入门项目，一边做着一边看看领域内其他小型开源项目的 API 是怎么设计的、代码是怎么写的。
