Chapter 15: Problem 40

True or False Private members of a private base class become inaccessible to the derived class.

Short Answer

Expert verified
Answer: True

Step by step solution

01

Understand Class Inheritance

In object-oriented programming, one class can inherit members and methods from another class. This is known as class inheritance. The class being inherited is called the base class or parent class, while the class that inherits members is called the derived class or subclass.
02

Understand Access Specifiers

Access specifiers determine the visibility and accessibility of class members. In C++ and similar languages, there are three access specifiers: public, private, and protected. Public members can be accessed from anywhere, while private members can only be accessed within the class they are defined. Protected members can be accessed in the same class and its derived classes.
03

Understand Private Base Class

A private base class means that the base class is inherited using the 'private' access specifier. When a class is derived privately from a base class, the public and protected members of the base class become private in the derived class. This means that they can only be accessed by member functions of the derived class, and are not accessible outside the derived class.
04

Analyze Statement

Now let's analyze the statement: "Private members of a private base class become inaccessible to the derived class." As mentioned earlier, private members are accessible within the class they are defined, and not accessible to derived classes. Since the statement refers to private members of a base class, they would already not be accessible in the derived class, regardless of whether the base class is private or not.
05

Determine True or False

Based on our analysis, the statement is true. Private members of a private base class indeed become inaccessible to the derived class. However, it is important to note that private members of a base class are already inaccessible to the derived class regardless of whether the base class is inherited privately or not.
