徒手找到 stdc++.h : 藏得挺深的

额外减小

使用dev-c++编程时，将光标移至头文件名处，会显示出路径。按ctrl+click可以查看内容。
然而，我在写c++的代码时，引用

1. #include <bits/stdc++.h>

复制代码

却一直没有显示。
（我也不知道是怎么回事，有大佬可以解释吗）

最近我在Dev-C++的文件夹里随便翻找时，竟意外找到了这个头文件！
进去一看，还真是包罗万象啊。。。

好像真的把平常用到的库函数都包含进去了。

最后附上找到的路径。挺长的，是吧

1. C:\Program Files (x86)\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++\x86_64-w64-mingw32\32\bits\stdc++.h
