I did a search before joining here but couldn't find anything relating to what I'm working on...
I have to make a Caesar cipher program that enters a phrase (using getchar), then enters the shift amount and outputs the encrypted phrase. I need to make sure it "wraps around" as if the input letter was z, and shift was 3, it would turn into c. I also need to make sure to only shift letters, not punctuation.
I have no idea how to even start basically, that's the only guidance I've got. We haven't gotten to strings so I have to use getchar somehow, or an array but I'm not sure how I would do that.
Any advice or help would be greatly appreciated.
