In this video tutorial you will learn how to write a program to check for perfect number using c language.
you will also learn to modify this source code to list the perfect numbers between a range of values for example between 1 – 100 or 1 – 1000.
In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positivedivisors excluding the number itself (also known as its aliquot sum).
For example, divisors of 6 are 1,2 and 3. The sum of these divisors is 6. So 6 is called as perfectnumber.
The next number is 28. This is followed by 496 and 8128.
I will also explain the logic used to construct this program and then will provide information on all the steps used in the source code.
