Perfect Number Generate

Assalamu Alaikum. Hope, you all are well by the grace of Almighty ALLAH. Today we learn how to find out the perfect numbers between two limits. Take a look at the Problem.

Problem: Write a program that prints the list of all perfect numbers between X and Y., where Y>X. User will input the value of X and Y. If X is not lower than Y, a message will be given "Invalid range".


A perfect number is one whose sum of factors is equal to the number like 6. 6 has three factors 1, 2, 3. When we add 1+ 2+ 3, it is equal to 6. Hence 6 is a perfect number. Likewise 28 is another perfect number.

Now, take a look at the program.

Thank You all.
