3. A Problem to Solve
Creating a video game with a group of classes to represent three types of boxes
Plain box
Toy box
Magic box
Begin by designing an ADT plain box
Use aspects of its implementation for the other two boxes

4. Class Declarations Private Data Fields Constructors and Destructors
Methods
Accessor methods
Mutator methods
Passing parameters by constant reference.

5. Class Declarations Guidelines for safe and secure programming
Declare data fields as private
Declare as const any method that does not change the object
Declare any parameter passed by reference as const
Unless you are certain it must be modified by the method
Preventing Compiler Errors

7. Inheritance Base Classes and Derived Classes
View Listing C1-5, Template header fi le for the class ToyBox
And the implementation file, Listing C1-6

8. Overriding Base-Class Methods
Redefine inherited methods
Example, Listing C1-7 Header file for the class MagicBox
And the implementation, Listing C1-8
Consider abstract class, an interface for the ADT Box, Listing C1-9
