xcode-select --install
这里是已经下载了
检验是否安装成功，终端输入
clang
如图所示是代表之前的command line tools安装 是安装成功的（Clang会不断更新的，更新位置系统更新中更新）
Download Visual Studio Code - Mac, Linux, Windows
四、完成配置（自定义创建位置，只要自己能记住安装位置即可）
文件后缀为.c是C文件，.cpp是C++文件
#include<stdio.h>
int main()
{
printf("Hello World\n");
return 0;
}
#include <iostream>
using namespace std;
int main()
{
cout<<"Hello World!"<<endl;
return 0;
}

7、 运行cpp文件，显示运行结果
