C Program to Check whether a given Number is Perfect Number



C Program to Check whether a given Number is Perfect Number

This C Program checks whether a given number is perfect number. Perfect number is a number which is equal to sum of its divisor. For eg,divisors of 6 are 1,2 and 3. The sum of these divisors is 6. So 6 is called as perfect number.

    #include <stdio.h>

    int main()

    {

        int number, rem, sum = 0, j;

        printf("Enter a Number\n");

        scanf("%d", &number);

        for (j = 1; j <= (number - 1); j++)

        {

            rem = number % j;

    	if (rem == 0)

            {

                sum = sum + j;

            }

        }

        if (sum == number)

            printf("Entered Number is perfect number");

        else

            printf("Entered Number is not a perfect number");

        return 0;

    }
