1 安装 VSCode

直接去官网(https://code.visualstudio.com/)下载并安装即可。

2 配置C/C++编译环境

• 方案一
  如果是在Windows，需要安装 MingW，可以去官网(https://sourceforge.net/projects/mingw-w64/)下载安装包。
  注意安装路径不要出现中文。
  

  打开 windows shell 界面，输入mingw-get install gcc、mingw-get install g++。
  如果安装的时候提示安装包被错误下载，可使用方案二安装。

• 方案二
  进入网址https://sourceforge.net/projects/mingw-w64/files/，下滑，下载图中所示压缩包。
  

  找一个无中文路径解压缩。
  添加环境变量。在Path中加入解压后的文件夹中的bin目录，如C:\ProgramFiles\MinGW\mingw64\bin。
  

  

• 测试
  在 windows shell 界面输入gcc -v、g++ -v，正确出现版本号则配置成功。

3 安装插件

搜索插件 C/C++ 和 Code Runner 并安装。

4 编辑配置文件

首先新建一个文件夹，并用 VSCode 打开。
在该文件夹中创建名为 .vscode 的文件夹。
在该文件夹中创建下面几个文件。以后的C/C++代码文件必须放在这个Code文件夹里，或者说有.vscode文件夹的文件夹里。

1. c_cpp_properties.json
   将 compilerPath 换成你的g++路径。

   {
     "configurations": [
       {
         "name": "Win64",
         "includePath": ["${workspaceFolder}/**"],
         "defines": ["_DEBUG", "UNICODE", "_UNICODE"],
         "windowsSdkVersion": "10.0.18362.0",
         "compilerPath": "C:\\MinGW\\bin\\g++.exe",
         "cStandard": "c17",
         "cppStandard": "c++17",
         "intelliSenseMode": "gcc-x64"
       }
     ],
     "version": 4
   }
   

2. launch.json
   将 miDebuggerPath 换成你的gdb路径。

   {
     "version": "0.2.0",
     "configurations": [
       {
         "name": "(gdb) Launch", 
         "type": "cppdbg", 
         "request": "launch", 
         "program": "${fileDirname}\\${fileBasenameNoExtension}.exe", 
         "args": [], 
         "stopAtEntry": false,
         "cwd": "${workspaceRoot}",
         "environment": [],
         "externalConsole": true, 
         "MIMode": "gdb",
         "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",
         "preLaunchTask": "g++",
         "setupCommands": [
           {
             "description": "Enable pretty-printing for gdb",
             "text": "-enable-pretty-printing",
             "ignoreFailures": true
           }
         ]
       }
     ]
   }
