30. Sum of Two Objects

 Create two classes: Point and Distance.

• Both classes store a private integer.
• Define a friend function named sumValues(const Point&, const Distance&).
   

This function should add the private integers from both objects and print the result in the format:

 Sum=<value>

In main():

• Read two integers (first for Point, second for Distance).
• Create objects of both classes.
• Call sumValues() to print the sum.
   

Example
 Input:

5 7

Output:

Sum=12

Input:

10 20

Output:

Sum=30
