            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "group": "build",
            "problemMatcher": []
        },
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe build active file",

                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {

4 main.cpp 测试
 

#include <iostream>

int main() {
    std::cout << "hello" << std::endl;
    return 0;
}

6 F5 或 ctrl+shift+b 运行(只是生成exe文件)
 生成 main.exe
 

7 在vscode终端运行

.\main.exe
