Google C++ Style
C++ is one of the main development languages used by many of Google's open-source projects. As every C++ programmer knows, the language has many powerful features, but this power brings with it complexity, which in turn can make code more bug-prone and harder to read and maintain.
The goal of this guide is to manage this complexity by describing in detail the dos and don'ts of writing C++ code . These rules exist to keep the code base manageable while still allowing coders to use C++ language features productively.
Style, also known as readability, is what we call the conventions that govern our C++ code. The term Style is a bit of a misnomer, since these conventions cover far more than just source file formatting.
Most open-source projects developed by Google conform to the requirements in this guide.
Note that this guide is not a C++ tutorial: we assume that the reader is familiar with the language.

using namespace std
有很多人不建议使用 using namespace std，还举了例子说很难区分其他比如自己写的函数到底是不是 std 中的。事实上，自己写的函数，应该有不同于 std 的命名空间，而且在使用的时候，要明显写出，如：udef::min()。
