assignment: 4.4. Internet mailers and news-readers often contain a "rot13"
function that can be used to "encrypt" words by
rotating their characters 13 positions
(i.e., A becomes N, B becomes O, C becomes P, ... Z becomes M).
This is convenient, because the same function can be used
to both "encrypt" and "decrypt" a word:
rot13("ROMEO") == "EBZRB"
and
rot13("EBZRB") == "ROMEO"
Write a Rot13() function that, given a string,
returns a string whose characters are those of the first string
rotated 13 positions.
(Hint: You may find the % operator to be useful.)


my program thus far and its error messages can be found at

If anyone can help me, I will be eternally greatful. Thank you

I lost my toe the other day...
then I looked down at my foot and found he'd come back to me.

Guess I'll think twice about putting toes in my mouth,eh?
