    Question STL Linked List of class within class

    I have a class Character in my program and I want to have three linked lists of Characters as members of that class.

    class Character
    {
    ...
    std::list <Character> one;
    std::list <Character> two;
    std::list <Character> three;
    };

    This will not work, however, because the Character class isn't complete (it goes into an STL file when debugging and gives me an error).
    I have tried a std::list of void * to try to push_back Characters later, but that doesn't work. I have also tried void *s to try to typecast them to std::list <Character> in the constructor, didn't work either. Anybody have any ideas on how I can do this? Thanx...

    Try lists of Character pointers.

    Why do you use three Character lists in a Character Class? I don't think this is a wise approach.

    Talking Zen's suggestion works!

    Thank you zen! You are brilliant! It now compiles and works.
    As for ozgulker, I don't quite understand your question. I didn't explain what kind of program I am making. I know that using three lists of Characters inside the class is one of the best ways I could approach my situation.
