在项目下新建文件夹【.vscode】，文件夹下新建两个文件（launch.json、tasks.json）。

目录结构示例如下：

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "gcc.exe - 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "S:\\IDE\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "将反汇编风格设置为 Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: gcc.exe 生成活动文件 ver"
        }
    ]
}

tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: gcc.exe 生成活动文件 ver",
            "command": "S:\\IDE\\mingw64\\bin\\gcc.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-fexec-charset=GBK"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

注意

1.请先安装编译器，如mingw64

2.将launch.json中【miDebuggerPath】后面的路径改为你安装编译器的路径加上\\bin\\gcc.exe

3.将tasks.json中【command】后面的路径改为你安装编译器的路径加上\\bin\\gcc.exe
