Write a shell script to find the exponent of a number?



echo  “ enter 2 numbers”
read a
read b
ex = 1
i = 1
while [ $i – li $h ]
do
ex = `expr $ex \* $a `
i= `expr $i + 1`
done

ALGORITHM VARIABLES: §   i:      loop counter of array. §   A:    array name. §   LB: lower bound. §   UB: upper bound. ALGORITHM: STEP 1:         set i =LB STEP 2:         repeat steps 3 & 4                            While i<=UB STEP 3:         apply process to A[i] STEP 4:         i = i+1            STEP 5:         exit EXPLANATION: §   To traverse the elements of the array, firstly set the loop counter ‘i’ equal to last element of the array called the LOWER BOUND. ...
