while test $num -gt 0

do

   temp=`expr $num % 10`          #extract the digit from nuber

   sum=`expr $sum +  $temp`      #add the digit into sum

   num=`expr $num / 10`             #reduce no by dividing the no by 10

   cnt=`expr $cnt + 1`                  #conter to count  the no of digit

done
