Write a program which reads a positive integer value N and indicates if N is a perfect number or not (N is a perfect number if N = the sum of its divisors without the number itself).

#include<stdio.h>
#include<conio.h>

int main()
{
	int N, i , sum;
	sum = 0;
	
	do{
	    printf("Enter an integer: ");
	    scanf("%d", &N);
	}while(N <0);
	
	for (i = 1; i< N; i++)
		if (N%i == 0)
			sum += i;
			
	if (N == sum)
		printf("%d is Perfect.\n",N);
	else
		printf("%d is not Perfect.\n", N);
 
	return 0;
}
