Question

Here is what I have so far, it is not working:

class Couple(o,t)
  one = o
  two = t
end

couple1 = Couple.new(10, "Ten")
p couple1.one
p couple1.two

Not sure why it’s not working?

Answer 1

Defining a class doesn’t work like defining functions, you have to define functions on them that use the internal variables, and the the initializer that tells it what to do when calling .new

attr_accessor helps with the crud of setting up the functions and variables. The most simplest ways would be to use have a class like

class Couple
  attr_accessor :one, :two
end

couple1 = Couple.new
couple1.one = 10
couple1.two = "Ten"
p couple1.one
p couple1.two

To use the new function to initialize the class with a few variables, you can define that function giving you a Class definition looking like

class Couple
  attr_accessor :one, :two

  def initialize(one, two)
    @one = one
    @two = two
  end
end

couple1 = Couple.new(10, "Ten")
p couple1.one
p couple1.two
