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","cStandard": "c17","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}]}]}

3. settings.json

{"files.associations": {"*.py": "python","iostream": "cpp","*.tcc": "cpp","string": "cpp","unordered_map": "cpp","vector": "cpp","ostream": "cpp","new": "cpp","typeinfo": "cpp","deque": "cpp","initializer_list": "cpp","iosfwd": "cpp","fstream": "cpp","sstream": "cpp","map": "c","stdio.h": "c","algorithm": "cpp","atomic": "cpp","bit": "cpp","cctype": "cpp","clocale": "cpp","cmath": "cpp","compare": "cpp","concepts": "cpp","cstddef": "cpp","cstdint": "cpp","cstdio": "cpp","cstdlib": "cpp","cstring": "cpp","ctime": "cpp","cwchar": "cpp","exception": "cpp","ios": "cpp","istream": "cpp","iterator": "cpp","limits": "cpp","memory": "cpp","random": "cpp","set": "cpp","stack": "cpp","stdexcept": "cpp","streambuf": "cpp","system_error": "cpp","tuple": "cpp","type_traits": "cpp","utility": "cpp","xfacet": "cpp","xiosbase": "cpp","xlocale": "cpp","xlocinfo": "cpp","xlocnum": "cpp","xmemory": "cpp","xstddef": "cpp","xstring": "cpp","xtr1common": "cpp","xtree": "cpp","xutility": "cpp","stdlib.h": "c","string.h": "c","iomanip": "cpp","array": "cpp","cstdarg": "cpp","cwctype": "cpp","memory_resource": "cpp","optional": "cpp","string_view": "cpp","unordered_set": "cpp","numeric": "cpp","list": "cpp","bitset": "cpp","chrono": "cpp","forward_list": "cpp","regex": "cpp","valarray": "cpp","cfenv": "cpp","charconv": "cpp","cinttypes": "cpp","codecvt": "cpp","complex": "cpp","condition_variable": "cpp","csetjmp": "cpp","csignal": "cpp","cuchar": "cpp","functional": "cpp","ratio": "cpp","future": "cpp","mutex": "cpp","scoped_allocator": "cpp","shared_mutex": "cpp","thread": "cpp","typeindex": "cpp","queue": "cpp","numbers": "cpp"},"editor.suggest.snippetsPreventQuickSuggestions": false,"aiXcoder.showTrayIcon": true,"cmake.outputLogEncoding": "auto","C_Cpp.errorSquiggles": "disabled"}

4. tasks.json

{"version": "2.0.0","tasks": [{"type": "cppbuild",                                     //任务执行的是shell命令"label": "C/C++: g++.exe build active file","command": "E:\\VSCode\\mingw64\\bin\\g++.exe",         //和launch.josn 中的 preLaunchTask 必须一样"args": ["-fdiagnostics-color=always",                       // 总是输出颜色代码，即便是在伪终端下"-g",//"${file}", // 编译当前打开（编辑）的 .cpp 文件"${fileDirname}\\*.cpp",                            // 编译当前打开的文件所在目录下的所有 .cpp 文件"-o","${fileDirname}\\${fileBasenameNoExtension}.exe",   // 生成的可执行程序的名字 ],"options": {"cwd": "E:\\VSCode\\mingw64\\bin"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true},"detail": "Task generated by Debugger."}]
}

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。
