Write a set of classes that represent a set of animals. There should be a Duck, Cat, and Dog instance that all implement an emote (**hint**: what sound does a duck make?) and a eat method. A constructor that takes a name as an argument should be defined elsewhere.

animals.rb

class Animal
  attr_reader :name

  def initialize(name)
    @name
  end
end


class Duck < Animal
    def emote
      "#{@name}'s quack"
    end

    def eat
      "#{@name} eats corn"
    end
end

class Dog < Animal
    def emote
      "#{@name}'s bark"
    end

    def eat
      "#{@name} eats bone"
    end
end

class Cat < Animal
    def emote
      "#{@name}'s meow"
    end

    def eat
      "#{@name} eats fish"
    end
end
