vscode cpp

工程结构应该是这样的。

└── foocpp
    ├── .vscode
    │   ├── launch.json
    │   └── tasks.json
    ├── README.md
    └── src
        ├── MainEntry.cpp
        ├── foo.cpp
        └── foo.h


1 open the folder foocpp with vscode
2 configure launch.json and tasks.json

//======================================
        launch.json
//======================================

            "MIMode": "lldb",
            "preLaunchTask": "build foocpp",
        }
    ]
}
