Source code bash shell Programming Algorithm

echo "Enter the number"

read num

sum=0

while test $num -gt 0

do

digit=`expr $num % 10`

num=`expr $num / 10`

sum=`expr $sum + $digit`

done

echo "sum of the digits= $sum"

OUPUT CS1252 Operating Systems lap

[redhat33@localhost jana]$ sh five.sh

Enter the number

12345

sum of the digits= 15
