在VS中使用万能头文件#include 编译错误的解决方法

codeforces已经有过说明。我这里只是把它翻译地更加浅显一点：

 

solution to include bits/stdc++.h in visual c++

 

By Tensor, 2 years ago, ,

• This is just a method i used to make me able to include bits/stdc++.h
• in visual c++.
• for those had minGW installed on PC :
• C:\MinGW\mingw32\lib\gcc\mingw32\4.8.1\include\c++\mingw32\bits
• copy this folder and then go to this adress
• C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include
• paste your folder. go to your visual studio project type bits you will see
• the auto-complete for the library and then choose stdc++.h
• for those don't have minGW:
• you should write your own header file and include all libraries in it then
• go to C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include
• make new folder name it "bits" and name the header file stdc++.h
• then paste it in "bits" folder.
• Hope this helps!
• Happy coding

就是说

1.若是安装了MinGW的直接在文件夹里面找到bits这个文件夹（注意里面必定要包含stdc++.h，貌似个人版本有两个bits文件夹），把里面内容复制粘贴到vs的头文件库（通常是在c盘的安装目录）里面。

（2017.3.19修正，装VS2017时候找了好一会，已经不是在这个地方，应该是先找到VS主目录，而后往这里面找VS主要目录\VC\Tools\MSVC\14.10.25017\include）

2.若是没有安装MinGW，那么本身在vs的include文件夹里面新建一个bits文件夹，里面新建一个名叫stdc++.h的头文件，里面写你经常使用的头文件，这里我搬运一下stdc++.h源文件：
