Write a C program to check whether a given number (N) is a perfect number or not? [Perfect Number - A perfect number is a positive integer number which is equals to the sum of its proper positive divisors. For example 6 is a perfect number because its proper divisors are 1, 2, 3 and it’s sum is equals to 6.] #include <stdio.h> int main() {     int N;     scanf("%d",&N); int i, sum=0;     for(i=1; i<N;i++)     {         if(N%i==0)             sum+=i;     }     if(sum==N)         printf("\n%d is a perfect number.",N);     else         printf("\n%d is not a perfect number.",N); } Input Output 8000 8000 is not a perfect number. 8128 8128 is a perfect number. 6 6 is a perfect number. 87 87 is not a perfect number.
