1、下载vscode，选择 Mac Universal版本。

2、安装插件 chiness、C/C++ Extension Pack、CodeLLDB

3、安装 Clang

4、新建文件 stdc++.h（/Library/Developer/CommandLineTools/usr/bin/stdc++.h）。具体代码在提示中。

5、桌面新建code文件夹，.vscode文件夹中新建tasks.json文件 和 lauch.json文件（具体提示中）

1、stdc++.h（/Library/Developer/CommandLineTools/usr/bin/stdc++.h）：
