源码研究之高效解决如何查看万能头文件bits/stdc++.h源码的问题（DevC++版）

其实有朋友学到一定程度就想研究源码，这是不错的，下面我来简要讲一下如何找到bit/stdc++.h源码

一般源码都在安装路径下的

D:\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++

或者

Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++\x86_64-w64-mingw32\32\bits

• 接着我们就可以用记事本或者notepad++打开了
