Write a program to be used as a calculator. It should be able to find addition ( + ), subtraction ( - ), multiplication (*), division (/), remainder of integer division ( % ), exponent (e), and square root (s) of numbers. The user enters inputs in the form: operator, number, (number); where the second number is not required for the exponent or square root. For example, if the user enters + 54, then the program prints out 9; or if the user enters s 64, the program prints out 8. Test your program for a wide range of possible inputs including division by zero and square root of negative values
