  scanf("%d",&min);

  printf("Enter the maximum range-: ");

  scanf("%d",&max);

  printf("Perfect numbers in the given range are-: ");

  for(n=min;n<=max;n++){

    i=1;

    sum = 0;

    while(i<n){

      if(n%i==0)

           sum=sum+i;

          i++;

    }

    if(sum==n)

      printf("%d ",n);

  }

  return 0;

}

output:

Enter the minimum range: 1

Enter the maximum range: 30
