Debug C++ lab

I have a c++ lab, yes it is school work and I have tested the code in small sections but trying to link them together I am getting a lot of errors. Project details: -you will debug the project and comment what was changed -you will explain why it was wrong in the comment, I am learning programming so I need to know how to fix it instead of having someone else do it every time. -Must have very good "American" English, this is a must -In total there are only 270 lines of codes including previous comments so its not a huge project ( using 80 character cut off ) -You have 1 hour to complete the project You will get the 3 files once you accept the job.
