Need help removing last character of every line if certain character

I need help removing the last character of every line if it is a certain character. For example I need to get rid of a % character if it is in the last position.

Input:
Code:
aaa%
%bbb
ccc
d%dd%

Output should be:
Code:
aaa
%bbb
ccc
d%dd

I tried this but it gets rid of all of the % characters. I just need the last one:

Code:
awk '//{gsub(/A$/,"")}{print}'

Are you, raptor25, and jgrosecl all part of the same group? One of you starts a thread and then later another seeks clarification or further advice on a permutation of the problem (same deal over at https://www.unix.com/unix-dummies-que...-question.html). If this is homework (which I'm inclined to believe given the nature of the questions), you need to take it to the homework forum and follow its rules.
