Initial Code

#You can open the class definition body of a singleton class and add instance methods, class methods, and constants
#You do this by using the 'class' keyword and a CONSTANT
class C
  def hello
    puts "this is a hello yo."
  end
end

module M
  def talk
    puts "hello."
  end
end

#Example 1
example1 = C.new
class << example1
  include M
end
#Call the Singleton method
example1.hello
#Call the Module Mix-in
example1.talk

#Example 2
example2 = C.new
example2.extend(M)
example2.talk
