6. Write a program to check whether a given number is a perfect number or not. Hint: A positive integer n is called a perfect number if it is equal to the sum of all of its positive divisors. excluding n itself For example, 6 is a perfect number. because 1. 2 and 3 are its proper positive divisors and 1 + 2 + 3 =. 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. The next perfect numbers are 496 and 8128

#include<stdio.h>

#include<conio.h>

void main()

{

          int val,i,j=0;

          clrscr();

          printf("\n\n\tEnter the Number to Check its Perfect or Not -> ");

          scanf("%d",&val);

          for(i=1; i<val; i++)

          {

                   if(val%i==0)

                   {

                             j=j+i;

                   }

          }

          if(j==val)

          {

                   printf("\n\n\t\tYour No is Perfect No");

          }

          else

          {

                   printf("\n\n\t\tYour No is not a perfect no");

          }

          getch();
