Write a function “perfect()” that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000

#include<stdio.h>

#include<math.h>

int main()

{

    int a;

    printf("Enter the number = ");

    scanf("%d",&a);                      ///asking limit of the function

    perfect(a);                          ///calling the function

}

 perfect(int a)

{

    int i,j,k,s,x;

   for(x=1;x<=a;x++)        ///for numbers from 1 to x

   {

         s=0;

        for(i=1;i<x;i++)                  ///for each number for factors

        {

               for(j=1;j<x;j++)

                 {

                         k=i*j;             ///checking whether it is factor or not like 2*3 =6

                         if(k==x)

                         {

                             s=s+i+j;        ///adding all the factors except 1 and itself

                         }

                 }

        }

             s=s/2;                        /// to avoid repetition lke 2*3  and 3*2

             s=s+1;                         /// adding 1 since 1 is also factor

            if(s==x)                         ///checking whether it is perfect number or not  6=1+2+3

            {

              printf("  %d ,",x);            ///printing each perfect number

            }

    }
