cs50 pset2 caesar: code works but it doesn't recognize spaces and punctuation

Question

My code works for a single word, but if I try to input a sentence, it output the encrypted text without any spaces or punctuation. How to use the function "ispunc" to solve the problem?

Answer 1

Maybe instead of that, you should be thinking about what the code should do if something is not alpha, when not to encode something, and what to do with a character when it isn't encoded, regardless of what kind of non-alpha it is.
