    Re: Problems with iterators

    I introduced them to std:artition() and erase(), and all of those problems that were plaguing that part of the code (for months) became resolved in less than 5 minutes.
    ...and the moral of the story is to know your STL algorithms!

    PS I wish that c++ tutors and books would remember the STL and give all of it the coverage it deserves - not just vectors, maps and i/o streams if you're lucky.
