hi all.

Im not sure whether this is the correct forum to post in, but here goes.

I've been given my first year (uni) project c++, a pretty small one really. Problem is I have written a code, but I havent tested or debugged it (dont ask). Can someone check it and correct any errors I have made, and suggest anyways i can improve it further. Thanks in advanced.

ps. Im not sure whether my program is actually doing the things the scenario wants me to do. I dont know whether Im on the right track so I have attached the scenario to this post, and if anyone could read the scenario and see if my code is the correct way forward etc.. Thanks.
