    c++ string

    How can I check that string name has at least one char, and has no char other than letters and hyphens?
    Especially the last part , how to check that it has just letters(either upper case or lower one) and no hyphens?

    To check if it's empty, use str.empty(), which returns true if it is empty and false if not. To check whether a string has any other characters, simply iterate through all of them and check them manually (isalpha), or use str.find_first_not_of().
