Firstly, heres an example of how its being used.

    std::string stringOne, stringTwo;
    while(1){
        std::cin >> stringOne, stringTwo;
        std::cout << "First string: " << stringOne << "\n";
        std::cout << "Second string: " << stringTwo << "\n";
        std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        std::cin.clear();
    }


The idea is to take two space delimited strings, and discard the rest of the input. For example, entering "one two three" would discard everything after "two". Both cin.ignore and cin.sync do the job, but I'm curious, whats the difference of them in this context?

cin.ignore() works everywhere, cin.sync() only on Windows (and possible other systems that decided that it makes sense for it to behave that way)
