Just a note on that one: I think this solution is inferior to doing

op.chomp!
if op == "Q"

or

if op.chomp == "Q"

Reason: on other platforms you might get a different terminating
character than \n.  Also the terminator is usually not considered part
of the input.  You could even go a step further and get rid of
whitespace thus allowing for more valid inputs:

op = gets.strip

Kind regards
