PERFECT NUMBERS IN BETWEEN MIN AND MAX VALUES :

PERFECT NUMBERS RANGE IN BETWEEN MIN AND MAX  : 

// program to illustrate min and max range of perfect number
#include<stdio.h>  // header section
#define pf printf // define section
#define sf scanf // define section
void main()
{
 int sum,min,max,n,i,temp;
 pf("\nEnter min number:");
 sf("%d",&min);
 pf("\nEnter max number:");
 sf("%d",&max);
 pf("\n Perfect number 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)
      pf("\n%d",n);
  }
}
