一、修改配置UI

按Ctrl + Shift + P打开命令调面板，并输入C/C++，并点击编辑配置”（UI）。

指定编译器路径或从下拉列表中选择检测到的编译器路径: C:\msys64\mingw64\bin\gcc.exe
IntelliSense 模式： windows-gcc-x64

二、构建任务

创建一个tasks.json来告诉vscode如何编译程序.

点击cpp文件
Ctrl + Shift + P打开命令调面板，并输入tasks.
点击配置默认生成任务
C/C++:g++.exe build active exe
按快捷键ctrl+shift+B，即可生成helloworld.exe等文件（表示成功）

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cppbuild",
			"label": "C/C++: g++.exe 生成活动文件",
			"command": "C:\\msys64\\mingw64\\bin\\g++.exe",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}\\${fileBasenameNoExtension}.exe"
			],
			"options": {
				"cwd": "${fileDirname}"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": {
				"kind": "build",
				"isDefault": true
			},
			"detail": "编译器: C:\\msys64\\mingw64\\bin\\g++.exe"
		},
	]
}

三、调试debug模式

创建一个launch.json文件

调试
添加配置
选择第二个C / C++Windows（Launch）
点选g++.exe…
将自动创建和打开文件launch.json

{
    "version": "0.2.0",
    "configurations": [
      {
        "name": "g++.exe - Build and debug active file",
        "type": "cppdbg",
        "request": "launch",
        "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${fileDirname}",
        "environment": [],
        "externalConsole": false,
        "MIMode": "gdb",
        "miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe",
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
          }
        ],
        "preLaunchTask": "C/C++: g++.exe build active file"
      }
    ]
  }
