Sample Input: 6 Sample Output: 6 is a Perfect Number (sum of factors of 6 is 6)

#include<stdio.h> int main() { int number, i; printf("Enter a Number: "); scanf("%d",&number); for(i=1; i <= number/2; ++i) { if (number%i == 0) { sum+=i; } } if(sum==number) { printf("%d is a perfect number ",number); } else { printf("%d is not a perfect number ",number); } return 0; }
