C++ Program 8

Write a C++ Program to create two classes each class consists of two private variables, an integer and a float variable. Write member functions to get and display them. Write a FRIEND function common to both classes, which takes the object of above two classes as arguments and the integer and float values of both objects separately and display the result.
