Detailed Description

A C++ Program to check whether a pair of numbers is an amicable pair or not.

An Amicable Pair is two positive integers such that the sum of the proper divisor for each number is equal to the other number.

Note

Remember that a proper divisor is any positive whole number that divides into a selected number, apart from the selected number itself, and returns a positive integer. for example 1, 2 and 5 are all proper divisors of 10.
