PERFECT NUMBER OR NOT

-

    

 

Consider the following I/O samples.


SAMPLE INPUT: 6

SAMPLE OUTPUT: PERFECT NUMBER


A number is called a PERFECT NUMBER if it is equal to the sum of it's positive divisors, excluding the number itself.


6 = Divisors of 6 are - 1,2,3  

1+2+3=6

6==6



C PROGRAM:

#include<stdio.h>

int main()

{

    int n,i,sum=0;

    scanf("%d",&n);

    for(i=1;i<n;i++)

    {

        if(n%i==0)

            sum+=i;

    }

    if(sum==n)

        printf("Perfect Number");

    else

        printf("Not a Perfect Number");

    return 0;

}


OUTPUT:





The given source code in C program "FOR PERFECT NUMBER OR NOT" is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
