I just started learning c++. I installed visual studio with “Desktop Development with C++”. CPlusPlus.com shows info for different c++ versions. How can I check which one I am using?

    See this for reference.

    Here’s a snippet:

    #if defined(__cplusplus) && __cplusplus >= 201703L
    std::cout << "compiler supports C++17" << std::endl;
#elif defined(__cplusplus) && __cplusplus >= 201402L
    std::cout << "compiler supports C++14" << std::endl;
#elif defined(__cplusplus) && __cplusplus >= 201103L
    std::cout << "compiler supports C++11" << std::endl;
#elif defined(__cplusplus) && __cplusplus >= 199711L
    std::cout << "compiler supports C++98" << std::endl;
#else
    std::cout << "compiler supports C++, standard unknown" << std::endl;
#endif

    To specify at compile-time, use g++ -std=c++17 for instance.
