    The reference must be initialized when you instantiate the struct. I believe in that case you've shown, you'd have to create a constructor for the struct that initialized the reference to something. There may be a problem with multiple instances of the struct as they might have all there c data members initialized to the same value (You'd have to check that out yourself).

    So I might as well use a class. Thanks.

    struct or class, it doesn't really matter that much, structs can have constructors and member functions just like classes do.
