There is no best way, here are 2 ways to mull over, first way gives you an idea 
of how to break out of a loop. The 2ns way show use of a do/while loop, that 
test for the loop condition is done at the end, not the start.

while(true)
    c = gets
    break if c.chomp == 'x'
end

or

begin
    c = gets.chomp
end while c != 'x
