我所使用的插件

红框中的五个插件是必备的，其中 Code Runner 插件可以在写完一个 .c 或 .cpp 文件后，按下 Crtl + R 快捷键快速编译运行单个文件。不用 Code Runner 也可以使用 C/C++ Complier 插件，如图二所示。

.json 文件配置

这里的 json 文件只是作为我个人的配置，仅供参考使用，并不能适用所有工程。而且配置没有一劳永逸，大部分情况下还是需要根据自己的项目来进行修改，我也在文件中做了部分解释，具体的自行 google。

这里附带一下 vscode 中 json 变量的含义，读者可自行前往查看：Variables Reference。

1. c_cpp_properties.json

{
    "configurations": [
      {
        "name": "Win64",
        "includePath": ["${workspaceFolder}\\**"],  // 表明前往工作空间下寻找包含文件
        "defines": ["_DEBUG", "UNICODE", "_UNICODE"],
        "windowsSdkVersion": "10.0.18362.0",
        "compilerPath": "E:\\VSCode\\mingw64\\bin\\g++.exe",

        "cppStandard": "c++17",
        "intelliSenseMode": "gcc-x64"
      }
    ],
    "version": 4
}

2. launch.json

    "version": "0.2.0",
    "configurations": [
      {
        "name": "(gdb) Launch", 
        "type": "cppdbg", 
        "request": "launch", 
        // 需要调试的可执行程序，与 tasks 中的可执行程序的名字需保持一致
        "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
        "args": [], 
        "stopAtEntry": false,
        "cwd": "${workspaceRoot}",
        "environment": [],
        // 该选项设置为 false 则使用外部控制台运行程序，程序结束时会立马关闭控制台，需要在末尾加上 system("pause") 
        "externalConsole": false,                               
        "MIMode": "gdb",
        "miDebuggerPath": "E:\\VSCode\\mingw64\\bin\\gdb.exe",
        "preLaunchTask": "C/C++: g++.exe build active file",    // 与 task 中的 label 需要保持一致
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
          }
        ]
      }
    ]
  }

如何运行

如何安装 vscode 以及如何安装插件我就不赘述了，读者可以自己搜索一下，这里仅介绍如何创建一个新项目。

新建一个文件夹 TEST，右键用 vscode 打开：

在 TEST 文件夹中新建 .vscode 文件夹，将四个 json 文件放进去（可以自己新建 .json 后缀的文件）：
在 vscode 中，创建 code 文件夹，创建 func.cpp，func.h 和 main.cpp 这三个文件，内容如下。

要注意，C++ 中自定义的头文件一定要用双引号 "" 括起来，而不是尖括号 <>，否则编译器会前往库文件中寻找头文件，找不到就会报 “func.h: No such file or directory” 的错误。

点击上方工具栏中的 Run->Run Without Debugging。

点击后会出现下面这个，点击红框中所示的选项。

最后就能成功运行了。
