The loop does not end when checking conditions

Question

This loop does not end after entering x. I'm really new to Ruby, and so far it is very different from what I learned before - quite interesting,

total = 0
i = 0

while ((number = gets) != "x")
    total += number.to_i
    i += 1
end

puts  "\nAverage: " + (total / i).to_s

Any help is greatly appreciated.

Because it getsgives you a new line. You need chompit.

Try:

while ((number = gets.chomp) != "x")

and you will see that it starts to work:

pax> ruby testprog.rb
1
5
33
x

Average: 13
