I've edited this project multiple times, but it never seems to compile. Any suggestions?

Your compiler should tell you what the errors are - here, they seemed to be fairly self-explanatory.

Try this (it compiles, but I've no idea if it works as I have no input file to test it.)

Thank you so much. Didn't know something so simple could be the problem.
