Output for Example #1 Arithmetic Operations on Character Variables is slightly incorrect.
First line of output should be "== Alphabets ==" not "== Characters==".

Yeah, that example is obviously wrong. I don't think that the term "alphabets" is correct, though. While that matches ctype_alpha(), isn't the proper term just "letters"? @Crell, @Girgias?

[Girgias]

I think so? Or using "English alphabet" could also work as letters like é are not affected.

[Crell]

"Alphabetic strings" vs "Alphanumeric strings"? Since the presence/absence of a digit seems to be the relevant factor here.

Thank you!
