{
    "configurations": [
        {
            "name": "f5 debug",//随便取
            "type": "cppdbg",//必选
            "request": "launch",//必选
            "program":"C:\\Windows\\System32\\cmd.exe",//这行和下一行控制弹出黑窗口不闪退
            "args": ["/c","${fileDirname}/${fileBasenameNoExtension}.exe","&","echo.","&","echo","----------","&","pause"],
            // "program":"${fileDirname}/${fileBasenameNoExtension}.exe",
            "stopAtEntry": false,//未知
            "cwd": "${fileDirname}",//必选
            "environment": [],//未知
            "externalConsole": true,//控制是否弹出黑窗口
            "MIMode": "gdb",//这行和下一行必须这样填，下一行是编译器目录
            "miDebuggerPath": "D:\\mingw64\\bin\\gdb.exe"
        }
    ]
}

这样写无法调试，但是不这样写又无法解决闪退问题
