Question

I have this function:

def func()
  puts "Give a value for x \n>"
  x = gets.chomp
  puts "Give a value for y \n>"
  y = gets.chomp

  z = x + y
  puts z
end

If a user inputs 5 for x and 5 for y, I want z to make 5 + 5 and print 10, but this will print 55 instead.

Answer 1

The values you’ve read are stored as strings, and with strings, the + operator performs concatenation. You need to convert both inputs to integers if you want to perform integer arithmetic:

z = x.to_i + y.to_i
