Lets write a C program to check if user entered number is a perfect number or not, using for loop.

Perfect Number: A number is called perfect number if sum of its divisors(except the number itself) is equal to the number.

For Example: If the user entered number is 28. The numbers which perfectly divide 28 are 1, 2, 4, 7, 14, 28. Leave 28 and add all other numbers. i.e., 1 + 2 + 4 + 7 + 14 = 28. So the entered number and the sum are equal. So 28 is a perfect number.
