    You'd need a queue<char>.

    Using the queue is no rocket science.
    I might be wrong.

    Is it a requirement of some exercise that you must use a queue? Can you just use the remove_if STL function and pass it a functor that equates to true for any space characters?

    And what have you tried? This describes exactly how you should proceed.

    The functions you might need:
    std::queue<char>: push - puts in the queue, pop - removes from the queue, top - looks up the current item, empty - tests if something left to read from the queue.

    std::string: operator[] - for looking up a character, operator+= - for appending (a character), clear - for emptying the string.
    I might be wrong.
