Lesson 17 Activity 1

/*
 * Lesson 17 Coding Activity 1
 * Write a program that will input a list of test scores in from the keyboard.
 * When the user enters -1, print the average.
 *
 * What do you need to be careful about when using -1 to stop a loop?
 *
 *     Sample Run:
 *         Enter the Scores:
 *         45
 *         100
 *         -1
 *
 *         The average is: 72.5
