Write a linux shell program to perform basic arithmetic operations using case

Basic arithmetic operations using case

Code:

clear echo ----------------------------------------------------- echo '\tEvaluation of Arithmetic expression' echo ----------------------------------------------------- echo Enter the a value read a echo Enter the b value read b echo 1.Addition echo 2.Subtraction echo 3.Multiplication echo 4.Division echo 5.Modules echo Enter your choice read choice case $choice in 1)echo Addition : $(expr $a + $b);; 2)echo Suubtraction : $(expr $a - $b);; 3)echo Multiplication : $(expr $a \* $b);; 4)echo Division : $(expr $a / $b);; 5)echo Modules : $(expr $a % $b);; *)echo This is not a choice esac

Output:

-----------------------------------------------------

1.Addition
2.Subtraction
3.Multiplication
