Ruby code not getting result [closed]

Answer 1

You are typing a string and expecting it to return an integer

Do this:

puts "How old are you?"
age = gets.chomp
if age == "10" 
  puts "Yo"
end

Answer 2

Yes, change it to

age = gets.to_i

Kernel#gets gives a string, you need to convert it to integer to do the integer comparisons. Read String#to_i method too.
