Self-test Exercise 17 asked you to overload the operator >>and the operator<< for a class Paris.complete and test this exercise.implement the default constructor and the constructors with one or two int parameters.the one-parameters constructor should initialize the first memeber of the pair;the second member of the pair is to 0 overload binary operator+to add pairs according to the rule
(a, b) + (c, d) = (a + c, b + d)
overload operator - analogously.
overload operator * on paris and int according to the rule
(a, b) * c =(a *c, b * c)
Write a program to test all the memeber function and overloaded operators in your class definition.
