通过快捷方式打开VS Code是编译不了的,需要对tasks.json修改(Tasks: Configure default build task)
先创建tasks.json

复制这段配置到tasks.json,记得修改VsDevCmd.bat的路径

{"version": "2.0.0","windows": {"options": {"shell": {"executable": "cmd.exe","args": ["/C",// The path to VsDevCmd.bat depends on the version of Visual Studio you have installed."\"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/Common7/Tools/VsDevCmd.bat\"","&&"]}}},"tasks": [{"type": "shell","label": "cl.exe build active file","command": "cl.exe","args": ["/Zi","/EHsc","/Fe:","${fileDirname}\\${fileBasenameNoExtension}.exe","${file}"],"problemMatcher": ["$msCompile"],"group": {"kind": "build","isDefault": true}}]
}

不能通过点击运行来运行,需要当作任务运行
