VS Code配置C++运行环境

环境配置

　在vscode中打开文件夹->创建新的文件夹->选中，这样就直接加入到vscode中了；或者直接把一个文件拖入vscode中。接着，在这个文件下创建一个.vscode文件夹（注意名字一定是.vscode），这是必须的（一般来说，每个文件夹中都会有这么一个.vscode配置文件）。注意：将此文件夹放在常用文件夹顶层，就不需要重复配置了。在.vscode文件夹中，新建三个配置文件，即launch.json、tasks.json、c_cpp_properties.json。将下列内容复制进去即可：

launch.json

{
    "version": "0.2.0",
    "configurations": [
      {
        "name": "(gdb) Launch",// 配置名称，将会在启动配置的下拉菜单中显示
        "type": "cppdbg", // 配置类型，这里只能为cppdbg
        "request": "launch",// 请求配置类型，可以为launch（启动）或attach（附加）
        "program": "${workspaceFolder}/${fileBasenameNoExtension}.exe",// 将要进行调试的程序的路径
        "args": [], // 程序调试时传递给程序的命令行参数，一般设为空即可
        "stopAtEntry": false, // 设为true时程序将暂停在程序入口处，一般设置为false
        "cwd": "${workspaceFolder}",// 调试程序时的工作目录，一般为${workspaceRoot}即代码所在目录
        "environment": [],
        "externalConsole": true,// 调试时是否显示控制台窗口，一般设置为true显示控制台
        "MIMode": "gdb",
        "miDebuggerPath": "D:\\Program Files\\mingw64\\bin\\gdb.exe",// miDebugger的路径，注意这里要与MinGw的路径对应
        "preLaunchTask": "g++",// 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
          }
        ]
      }
    ]
  }

tasks.json

{
    "version": "2.0.0",
    "command": "g++",
    "args": ["-g","${file}","-o","${fileBasenameNoExtension}.exe"],   
    "problemMatcher": {
        "owner": "cpp",
        "fileLocation": ["relative", "${workspaceFolder}"],
        "pattern": {
            "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "severity": 4,
            "message": 5
        }
    }
}

c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../include",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed",
                "D:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "D:/Program Files/mingw64/bin/g++.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

测试例子

在文件夹里面新建一个main.cpp

代码如下：

#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main()
{

    vector<string> msg {"Hello", "C++", "World", "from", "VS Code!"};

    for (const string& word : msg)
    {
        cout << word << " ";
    }
    cout << endl;
    getchar();
}

运行结果：
