Mac 终端怎么使用“bits/stdc++.h”头文件

我前面的文章写到Xcode怎么用“bits/stdc++.h”头文件https://blog.csdn.net/u013241595/article/details/99412978，但是这个只能Xcode用，在终端用不了，下面说一下在终端怎么用“bits/stdc++.h”头文件

找到Macintosh HD这个磁盘

进去点资源库

找到Developer点进去

找到CommandLineTools点进去

找到usr点进去

找到include点进去

在里面新建一个bits文件夹，然后进入这个文件夹

在里面新建一个stdc++.h文件

最后将下面内容复制到这个文件中，然后保存就好了

现在大功告成可以打开终端试一下头文件是不是可以正常使用了
