How to create a calculator using switch case and?

There are four possible values of op i.e. ‘+’, ‘-‘, ‘*’ and ‘/’. For case ‘+’ perform addition and store result in some variable i.e. result = num1 + num2. Similarly for case ‘-‘ perform subtraction and store result in some variable i.e. result = num1 – num2. Repeat the process for multiplication and division. Finally print the value of result.
