Question

I wrote a small program to test out Textmate 2 (I’m fairly new to Ruby) and it’s spitting out that 4 + 9 = 49 instead of 13 for some reason.

def add(x,y)
  c = x + y
  return c
end

puts "please enter a value "
a = gets.chomp
puts "please enter another value "
b = gets.chomp

printMe = add(a,b)

puts printMe

Answer 1

It’s because gets returns a string:

def add(x,y)
  c = x + y
end

puts "please enter a value "
a = gets.to_i
puts "please enter another value "
b = gets.to_i

printMe = add(a,b)

puts printMe
