-//Software Exercise:
+//Software Exercise 4:
 //1. Update the software system by creating a new library, which includes 
 //   a class that defines the behavior of a bouncing ball on the LCD screen.
 //2. Demonstrate the system with two or more bouncing balls on the screen.
 //3. Show that the system resets the ball locations when you hold the 
 //   accelerometer upside down.
