    If I am not wrong, only iterators from std::vector and std::string are random access iterator.

    You might write your own container with random-access iterators...

    There is std::iterator_traits that can tell you the category of an iterator. This requires some extreme template programming, of course.

    Oh, and std::deque is, I believe, random access.
