手动添加bits/stdc++.h到vs2017的步骤是怎样的

这篇文章给大家介绍手动添加bits/stdc++.h到vs2017的步骤是怎样的，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

本机环境：win10系统 64位 vs2017

最近码代码时偶然发现了bits/stdc++.h这个头文件（万能头文件），基本上所有的代码只要用了这个头文件就不再写其他头文件了。

看到它就仿佛开启了新世界（也有缺点，就是导致编译速度变慢，不过一般可以忽略不计）。

【如果安装了MinGW的直接在文件夹里面找到bits这个文件夹，把里面内容复制粘贴到vs的头文件库里面】

1 .新建txt文档，把以下代码（stdc++.h源码）复制进去：

2. 把txt文档改名stdc++.h

3. 打开vs2017的安装目录

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include格式类似上面

在“include”目录下新建文件夹“bits”，然后把刚才的bits/stdc++.h移入。

4. 大功告成
