  def initialize(name)
    @name = name
  end

  def bark!
    puts "I'm a #{self.class} and my name is #{name}!"

end


# put this in another file, stored in the same directory as the "dog.rb" file above
require_relative 'dog'

class Poodle < Dog
end

p = Poodle.new('Sally')
p.bark!

# execute via "cd-ing" into the directory with poodle.rb, then:
# ruby poodle.rb
