vscode中task.json和launch.json的关系

 tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "dog",
            "type": "shell",
            "command": "g++",
            "args": ["-g", "${file}", "-std=c++11", "-o", "${fileBasenameNoExtension}.out"]	//相当于 g++ -g main.cpp -std=c++11 -o main.out
        }
    ]
}

launch.json

{    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,	//如果不要窗口弹出，在ide中显示，就设置成 false
            "MIMode": "gdb",
            "preLaunchTask": "dog",   //表示预先生成一个中间文件，用于g++运行
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

 坐标的label要跟 右边的 "preLaunchTask"对应。

  "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",则是制定要运行或者调试的可执行文件
