How do i increment letters in c++?

Question

I\'m creating a Caesar Cipher in c++ and i can\'t figure out how to increment a letter.

I need to increment the letter by 1 each time and return the next letter in t

Answer 1

It works but don't forget that if you increment 'z' you need to get 'a' so maybe you should pass by a check function that output 'a' when you get 'z'.
