    adding strings to container

    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?

    Code:
    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.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
