使用vscode运行cpp确实挺麻烦的，需要配置几个文件，简单来说：

• c_cpp_properties.json 用来配置编译器和编译选项
• launch.json 用来配置运行时选项
• tasks.json 用来配置debug选项

.vscode/c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang++",
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "macos-clang-x64"
        }
    ],
    "version": 4
}

.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "mydb",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "cwd": "${workspaceFolder}",
            "preLaunchTask": "Build with Clang"
        }
    ]
  }
  

注意type改成lldb，program选项填生成的可执行文件，cwd选项填当前工作路径，preLaunchTask选项填写tasks.json的label。

.vscode/tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build with Clang",
            "type": "shell",
            "command": "clang++",
            "args": [
                "-std=c++17",
                "-stdlib=libc++",
				"-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "--debug"
            ],
            "group": "build"
        },
    
    ]
}

注意label选项，type应该无所谓，args要填对，-g是要编译的文件，-o是编译输出文件名。
