Description

This lab shows how to use the if statement and the while loop. It asks the user to enter two numbers and to choose a selection and the program will run based on the selection the user chose. After it runs, if the user didn’t use the number 0, the program will ask for two more numbers and run again till the user decides to put a 0 in one of the number choices.
