In this chapter you learned the basics of classes. Now you’ll begin “fleshing out” aspects of a class called “Hybrid Vehicle.” Hybrid vehicles are becoming increasingly popular, because they often get much better mileage than purely gasoline-powered vehicles. Browse the web and study the features of four or five of today’s popular hybrid cars, then list as many of their hybrid-related attributes as you can. For example, common attributes include city-miles-pergallon and highway-miles-per-gallon. Also list the attributes of the batteries (type, weight, etc.).
