**a) Write a shell script that computes the gross salary of a employee according to the following**

**1) if basic salary is <1500 then HRA 10% of the basic and DA =90% of the basic**

**2) if basic salary is >1500 then HRA 500 and DA =98% of the basic**

**The basic salary is entered interactively through the key board**

**(b)Write a shell script that accepts two integers as its arguments and computes the value of first number raised to the power of the second number**

echo " Enter the Salary "

read sal

if [ $sal<1500] then

da=`expr $sal*90/100`

hra=`expr $sal*10/100`

gsal=’expr $sal +$hra+$da

echo “$gsal”

elif [$sal>1500]

hra=500

da=’expr $sal*98/100’

gsal=’expr $sal+$hra+$da

gross=`expr $sa + $da + $hra`

fi

fi

(b)

a=$1

b=$2

c=pow($a,$b)

echo”$c”
