推荐答案

预编译头文件通过在其中添加经常需要的包含文件来减少编译时间.
查看Google或此Wikipedia链接:
http://en.wikipedia.org/wiki/Precompiled_header [

Precompiled headers are used to reduce the compile time by adding often required include files there.
See Google or this Wikipedia link:

I would recommend, that you add the include files that most of your other application code requires to the stdafx.h. This significantly reduces the time to build your project.
