Answer 1

没有配置好环境
把launch.json文件写入下面的
也可以看这篇文章https://blog.csdn.net/ambition_zhou/article/details/104509116
miDebuggerPath 改成 自己电脑的gdb 的路径

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(Windows) Launch",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "cmd",
            "preLaunchTask": "echo",
            "args": [
                "/C",
                "${workspaceFolder}/${fileBasenameNoExtension}.exe",
                "&",
                "echo.",
                "&",
                "pause"
            ],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole":true
        },
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "D:\\Programming\\mingw64\\bin\\gdb.exe",// 自己电脑的gdb
            "preLaunchTask": "echo",//这里和task.json的label相对应
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
 
        }
    ]
}

c_cpp_properties.json这个文件类似于下面的，添加进自己的库

    "configurations": [
        {
            "name": "Win32",
