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

Expert verified
Question: Create the first line of a class declaration for a class called "Soundsystem" that inherits from three other classes: CDplayer, Tuner, and CassettePlayer using public inheritance in C++. Answer: `class Soundsystem : public CDplayer, public Tuner, public CassettePlayer { };`

Step by step solution

01

Start with the class declaration

To begin, we need to declare the Soundsystem class using the 'class' keyword. class Soundsystem
02

Add the multiple inheritance

Next, we should inherit from the three base classes (CDplayer, Tuner, CassettePlayer) using the colon ':' and specifying public inheritance for each class. class Soundsystem : public CDplayer, public Tuner, public CassettePlayer
03

Add the opening brace and semicolon

Since this exercise asks only for the first line of the declaration, we can add the opening brace '{' to indicate the start of the class definition, but we won't add any members or methods. Don't forget to add the semicolon ';' to close the class declaration. class Soundsystem : public CDplayer, public Tuner, public CassettePlayer { }; Now, the Soundsystem class correctly inherits from the CDplayer, Tuner, and CassettePlayer classes using public inheritance.
