在VS中使用萬能頭文件#include 編譯錯誤的解決方法

codeforces已經有過說明。我這裏只是把它翻譯地更加淺顯一點：

 

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

就是說

1.若是安裝了MinGW的直接在文件夾裏面找到bits這個文件夾（注意裏面必定要包含stdc++.h，貌似個人版本有兩個bits文件夾），把裏面內容複製粘貼到vs的頭文件庫（通常是在c盤的安裝目錄）裏面。

（2017.3.19修正，裝VS2017時候找了好一會，已經不是在這個地方，應該是先找到VS主目錄，而後往這裏面找VS主要目錄\VC\Tools\MSVC\14.10.25017\include）

2.若是沒有安裝MinGW，那麼本身在vs的include文件夾裏面新建一個bits文件夾，裏面新建一個名叫stdc++.h的頭文件，裏面寫你經常使用的頭文件，這裏我搬運一下stdc++.h源文件：
