Enhanced Calculator

Create a program called Calculator which has the same functionality as the one in the switch example, except with more features!

Here's where we're going to make use of the modulus operator which gives the remainder of a division problem. Add the % operator as one possible option for the user to choose and utilize.

You should also change the operator choices. For example, instead of prompting the user for "add" or "subtract", prompt them for the characters '+' and '-'. Note: You can assume that the operator given by the user is the first character in the line, since there is no nextChar() method for Scanner.
