Thread: replacing charcters for other characters

hey, im a bit stuck with this programming assignment ive been playing around with

i basically have to take a word ( or serval words) and code them

with an offset provided by the user so

a=b is the 1st offset
a=c is the 2nd offset

and so on

ive written this as a test , but it doesnt print the final word

any help???

++++++++++++
(btw... i know i havent covered all the possiblitties but this is just a test)++++++++++
