Abundant Number.cpp

/*
This program check if the user Input(integer) number is a Abundant number or not.Also Print the Abundant Number Upto Given input number.

If the sum of factors of a number is greater than twice that number, it is considered to be Abundant Number.

For example:
12 is an Abundant number.

-> Sum of Factors of 12 is:
1 + 2 + 3 + 4 + 6 + 12 = 28

-> Twice of 12 is :
12 * 2 = 24

-> Sum of Factor of 12 is Greater than Twice of 12.
