NoMethodError: undefined method `type' for 8:Fixnum

Working through an intro Ruby exercise with this code:

num = 8
7.times do
  print num.type, " ", num, "\n"
  num *= num
end

I keep getting:

NoMethodError: undefined method `type' for 8:Fixnum

Do i have to define type? I thought this was a method that ruby recognized

Solution

  • The type method used to return an object's class but was deprecated a long time ago (back in the 1.8 days) and subsequently removed.

    You can use the class method instead, however if you are following a tutorial or something similar this is a sign that it is very old - possibly 10 years old!
