CalculatorApp Assignment

I created an app that prompts the user to choose from addition, subtraction, multiplication, division and square root functions. Once they select, they are prompted to give two numbers (or one number, in the case of the square root), and the program will do the calculation and return the result.

The program asks users if they would like to do another calculation after each one is completed, and they can either choose to continue, or quit. There is also error handling for bad input.
