I have no clue what I'm doing wrong... plz help (C++)

I'm currently working on my C++ assignment and I can't see where my mistake is. My buddy tried to help me but neither of us can quite figure it out. Btw, I'm not allowed to use vectors in this program which I feel like would make it a lot easier. Any and all help will be very much appreciated.
