    one of the STL libraries

    I don't know which one it is. I've never used the STL before, and I'm just getting started, and finding that using it doesn't appear to be horribly difficult. I just need clarification on one thing... which one of the libraries is like a linked list, but only adds a new element if it doesn't exist anywhere else in the list? Like, if I tried to added "1,2,3,4,5,6" to the list, and then tried to add 5 again, it wouldn't do anything. Hmmm... I think there is one. Am I wrong?
    Away.

    There's only one STL. What you're looking for is an STL container.

    std::list also has a function, unique() which removes adjacent identical elements.
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    Also note, <algorithm> defines a generic std::unique algorithm which does the same.

    Just remember the key thing with the unique function is that the elements in the container are required to be sorted prior to its use.
