adding strings to container

[KIBO]

Is there a way with 1 line of code that reads strings from standard input and only adds the strings that are less than 5 characters long?

something like this but then with a predicate?

copy(istream_iterator<std::string>(std::cin), 
        istream_iterator<std::string>(), 
        back_inserter(v)); // add only certain ones?

Perhaps by using copy_if with a predicate.
