Ruby while loop

Question

Writing a ruby while loop that take integers as an input and stores them in an array when a certain integer is entered (-1) the loop should stop and print out the array. When -1 is entered the loop stops but there is no output.

puts " Enter a number"

x = -1.to_i
number = ' '
numbers = []

while number != x
    number = gets.chomp
    numbers.push(number)
  end


puts
numbers.pop
p numbers

"When -1 is entered the loop stops ..." – with the given code, it will just keep looping. — Stefan

The loop will never stop gets.chomp returns a String so the loop will go on for ever because:

"-1" != -1 
#=> true

Try changing this to:

while number != x
  number = gets.chomp.to_i
  numbers.push(number)
end
