called deficient if the sum of its divisors is less than the
original number. A number is called abundant if the sum
of its divisors is more than the original number. Write a
program that answers the following questions: What
numbers below 5000 are perfect? What odd numbers
below 5000 are abundant? What are the relative
proportions of deficient, abundant, and perfect numbers?
5000 should be in a global constant.
