Write a C++ program creates two distance class find sum and difference using friend function
Assignment 23
Create two classes dist1 (meters, centimeters) and dist2
(feet, inches). Accept two distances from the user, one in meters and
centimeters and the other in feet and inches. Find the sum and difference of
the two distances. Display the result in both (meters and centimeters) as well
as feet and inches (use friend function).
