#include <iostream>

int main()
{
    int a{7}; // it is not supported in VS code
    std::cout << a << '\n';
    return 0;
}

当我按run时，终端会显示这样的命令-

$cd“/users/xxxx/desktop/C++/C++/”&& g++example.cpp-o example&& “/users/xxxx/desktop/C++/C++/”示例

我想在编译时将基本命令更改为

$cd“/users/xxxx/desktop/C++/C++/”&& G++示例。cpp-std=C++17-O示例&& “/users/xxxx/desktop/C++/C++/”示例

所以我不必每次执行时都键入'-std=C++17'。
