Compare Files and Output Difference
I have to compare two files for any differences, then output the lab and question number for any differences. This is what I currently have:

diff lab2.txt lab2answer.txt > lab2compare.txt

Though the output doesn't have to be sent to a .txt (or any sort of log), I found that easier, at least for the time being. Now, I'm stuck on how to report back the lab and question number that has differences.

what do you mean by report back??

What it has to do is, after comparing the files, state, or echo I suppose would be the right term, which ones differed.

Ex.: After comparing lab2.txt w/ lab2answer.txt, it finds that my results for cmd/question 3 differ from the results given in the answer key (provided by the professor). I need it to echo/state/report that "Lab 2, Question 3 differ."

Does that make sense?
