Precompiled file Stdafx.h
Get bored of waiting when compiling a programme? Especially your project contains lots of standard libraries----which are huge and you really should not change anything inside. Well, use stdafx.h to precompile them into .PCH file, you you don't need to compile them each time.
Note, at the very top of each cpp file, put #include "stdafx.h" there!
Generate a stdafx.h, and put all the header files you want to precompile there.
