Nkhosinathie-
You are a member now, and as such, you are expected to know how and when to use code tags. If you need to, please
review how and when to use them.
Okay, so you posted an extremely large program, did you expect it to be magically changed by us, or did you have a question on how to do it? Most of the keywords and control structures are the same from C to C++, so I would recommend you start by changing the libraries, changing the print statements (though if you put the right include in, you don't really have to), and going from there.
Unless there was a more specific question?
