Windows下配置vscode运行c++

• Windows下配置vscode运行c++
• 前言
• 一、下载/安装g++、gdb
• 二、使用以下配置
• • 1.launch.json
  • 2.tasks.json
  • 3.c_cpp_properties.json
  • 安装插件：C/C++、C/C++ Runner
  • 问题

记录vscode如何运行c++程序

windows下如何下载g++以及gcc

修改了一下如何使用vscode运行和调试c/c++程序中launch.json需要自行修改的部分，以下可以直接复制粘贴使用

代码如下（示例）：

{
    "version": "0.2.0",
    "configurations": [
      {
        "name": "(gdb) Launch",
        "type": "cppvsdbg",//膜拜https://blog.csdn.net/Dear_Atri/article/details/123057682
        "request": "launch",
        "program": "${fileDirname}\${fileBasenameNoExtension}.exe",
        "args": ["g++","/C","${fileDirname}/${fileBasenameNoExtension}.exe", "&", "pause"],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": true,
        "internalConsoleOptions": "neverOpen",
        "MIMode": "gdb",
        "miDebuggerPath": "gdb.exe",
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": false
          }
        ],
        "preLaunchTask": "Compile"
      },
      {
        "name": "C/C++ Runner: Debug Session",
        "type": "cppdbg",
        "request": "launch",
        "args": [
          ""
        ],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}", // 调试程序时的工作目录
        "environment": [],
        "program": "${fileDirname}/${fileBasenameNoExtension}.exe", // 将要进行调试的程序的路径
        "internalConsoleOptions": "openOnSessionStart",
        "MIMode": "gdb",
        "miDebuggerPath": "gdb",
        "externalConsole": false,
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
          }
        ]
      }
    ]
  }

代码如下（示例）：

{
    "version": "2.0.0",
    "tasks": [{
        "label": "Compile", // 任务名称，与launch.json的preLaunchTask相对应
        "command": "g++",   // 要使用的编译器，C++用g++
        "args": [
            "${file}",
            "-o",    // 指定输出文件名，不加该参数则默认输出a.exe，Linux下默认a.out
            "${fileDirname}/${fileBasenameNoExtension}.exe",
            "-g",    // 生成和调试有关的信息
            "-m32",  // 不知为何有时会生成16位程序而无法运行，此条可强制生成64位的
            // "-Wall", // 开启额外警告
            "-static-libgcc",     // 静态链接libgcc，一般都会加上
            "-fexec-charset=GBK", // 生成的程序使用GBK编码，不加这条会导致Win下输出中文乱码；繁体系统改成BIG5
            "-D__USE_MINGW_ANSI_STDIO", // 用MinGW写C时留着，否则不需要，用于支持printf的%zd和%Lf等
        ], // 编译的命令，其实相当于VSC帮你在终端中输了这些东西
        "type": "process", // process是把预定义变量和转义解析后直接全部传给command；shell相当于先打开shell再输入命令，所以args还会经过shell再解析一遍
        "group": {
            "kind": "build",
            "isDefault": true // 不为true时ctrl shift B就要手动选择了
        },
        "presentation": {
            "echo": true,
            "reveal": "always", // 执行任务时是否跳转到终端面板，可以为always，silent，never。具体参见VSC的文档，即使设为never，手动点进去还是可以看到
            "focus": false,     // 设为true后可以使执行task时焦点聚集在终端，但对编译C/C++来说，设为true没有意义
            "panel": "shared"   // 不同的文件的编译信息共享一个终端面板
        }
        // "problemMatcher":"$gcc" // 捕捉编译时终端里的报错信息到问题面板中，修改代码后需要重新编译才会再次触发
        // 本来有Lint，再开problemMatcher就有双重报错，但MinGW的Lint效果实在太差了；用Clangd可以注释掉
    }]
}

{
    "configurations": [
      {
        "name": "windows-gcc-x64",
        "includePath": [
          "${workspaceFolder}/**"
        ],
        "compilerPath": "C:\MinGW\bin\g++.exe",//安装g++默认路径
        "cStandard": "${default}",
        "cppStandard": "${default}",
        "intelliSenseMode": "windows-gcc-x64",
        "compilerArgs": []
      }
    ],
    "version": 4
  }

每次使用F5运行时出现以下提示

终端将被任务重用，按任意键关闭。
