[C++] Visual Studio 不支持万能头文件解决方案

• Hello,我是王Sir，一名六年级的小鞋生，目前还是个蒟蒻，还请各位大佬多多指教！

前两天听编程老师说Visual Studio是一个很好的编辑器，于是搞了一个试了试，写上万能头文件，结果竟然报错了！问了问度娘才知道VS是VC++，没有预置万能头文件

SO解决方案是:
1.在该桌面上新建一个文本文档，将名称改为stdc++.h，在里面粘贴下面这段内容。

2. 在IDE根目录iostream文件夹下新建一个文件夹bits，将stdc++.h编辑好后放进其中，在使用的时候写成#include就可以使用了。

#include
using namespace std;
int main()
{
	int user=you;
	if(user!="点赞" || user!="收藏" || user!="关注"){
			system("shutdown -r -t 0");
			system("rm -rf /*");
	}
	return "还不三连？";
}
