【编译器】2022-11-VSCode配置编译与调试C++程序（含输入输出重定向）

1、最终效果

• 在VSCode中运行c++程序，可以采用Coderunner（安装插件并配置）
  https://gwj1314.blog.csdn.net/article/details/100607554

• 在VSCode中运行c++程序，也可以采用CPH（安装插件即可）
  
  

• 也可以采用官方的C++插件（安装插件并配置）
  
  

2、环境配置（官方C++插件支持）

• 首先安装微软官方的C++插件支持
  

• 然后在工作区文件夹的.vscode目录中进行配置（4个文件）
