nice code!So are we supposed to guess what you want. Does it return errors? Does it behave in a way you don't want?Do you have a question?BTW, this is a forum for WEB languages...which C++ isn't, so you may find it hard to find help on that subject.I have been learning c++ for a couple months now, so I might be able to help.
