codeforce能用万能头文件吗_VScode 无法使用C++万能头文件#include<bits/stdc++.h> 解决方案...

在刷题的时候，使用万能头文件 #include，但是vscode无法识别，找不到头文件。

问题出在路径中没有这个文件，所以创建这个文件。

红波浪线报错

解决方案，亲测有效

在代码的头文件加入#include，右键转到定义

在打开的iostream文件上右键“在finder中显示”，找到该文件所在的文件夹(win系统同理)

在该文件夹下，新建一个txt文件，将名称改为stdc++.h，粘贴下面这段内容到里面，并将文件保存在此。

#if __cplusplus >= 201103L

#include

现在再运行代码#include，应该就没问题了。

(或者在上述iostream同级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也可以。
