为VS添加bits/stdc++.h头文件

这两天才发现#include<bits/stdc++.h>的神奇之处，一个它几乎包含了所有的头文件啊，省了好多事！但有利就有弊，他比较消耗时间，但和总体相比，还是值得的。
这里面一般路径不太好找，我的如下：

你们可以参考一下。
接下来，添加步骤

1. 【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】

2. 如果没有安装MinGW，那就跟着我来做以下步骤：

   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. 打开我上面给的目录（一般在C盘里面，而且不太好找）
4. 然后依次打开文件夹“14.15.26726”“include”
   在“include”目录下新建文件夹“bits”，然后把刚才的bits/stdc++.h移入。
   
   
   关闭vs再次打开就发现已经存在了。
