Chapter 15: Problem 35

Write the first line of the declaration for a SoundSystem class. Use multiple inheritance to base the class on the CDplayer class, the Tuner class, and the cassetteplayer class. Use public base class access in all cases.

Short Answer

Answer: `class SoundSystem : public CDplayer, public Tuner, public cassetteplayer {};`

Step by step solution

Include Necessary Header Files

You must include the header files containing the CDplayer, Tuner, and cassetteplayer classes to be able to inherit from them in the SoundSystem class declaration. Let's suppose these classes are defined in cdplayer.h, tuner.h, and cassetteplayer.h files, you would include these at the beginning of your source code: ```cpp #include "cdplayer.h" #include "tuner.h" #include "cassetteplayer.h" ```

Declare the SoundSystem class

Now, declare the SoundSystem class with its multiple inheritance. Use the colon (:) to indicate that the SoundSystem should inherit from the other classes, and specify public inheritance access for all base classes. Here's the first line of the class declaration for the SoundSystem: ```cpp class SoundSystem : public CDplayer, public Tuner, public cassetteplayer { ```

Complete SoundSystem Class Declaration

Add any member variables/functions you want in the SoundSystem class and close the class declaration with a semicolon (;). In this example, since the required information is only about the first line of the class declaration related to inheritance, we'll simply close the class here. ```cpp class SoundSystem : public CDplayer, public Tuner, public cassetteplayer { }; ``` Now the SoundSystem class has been successfully created with multiple inheritance from the CDplayer, Tuner, and cassetteplayer classes using public base class access.
