How could we make it easier to print Fraction's?

Some possibilities:

• Write a non-member function in the test program:

  void print(const Fraction& f);          
           
  

• Write a member function, print, in the Fraction class:

  class Fraction
  {
  ...
    void print();
  ...
  };          
           
  

• Write a non-member overloaded operator<< and have the Fraction class make it be a friend.
• Write a non-member overloaded operator<<
