Answer: True

Step by step solution

Understand Inheritance in C++

Inheritance is the process by which a new class (derived class) is created from an existing class (base class), allowing the derived class to inherit properties and methods from the base class, without changing the original base class.

Know the Access Specifiers in C++

In C++, there are three access specifiers - private, protected, and public. These specifiers control the access to class members (variables and methods) as follows: 1. Private: Accessible only within the class or by the class's member functions. 2. Protected: Accessible within the class and its derived classes. 3. Public: Accessible anywhere the class object is accessible.

Understand Inheritance Modes in C++

In C++, when creating a derived class, it is possible to specify the inheritance mode, which determines how the base class members will be accessible in the derived class. There are three inheritance modes: 1. Public Inheritance: Base class access specifiers remain unchanged in the derived class. 2. Protected Inheritance: Base class public and protected members become protected in the derived class. 3. Private Inheritance: Base class public and protected members become private in the derived class.

Analyze the impact of the base class's access specification on the derived class

As explained in the previous steps, the base class's access specification influences the way derived class accesses the base class members because the accessibility of each member in the derived class will depend on both the base class's access specifier and the inheritance mode. For instance, if a member is declared private in the base class, it will still be private in the derived class regardless of the inheritance mode used to create the derived class.

Determine the Answer

Based on the understanding of inheritance and access specifiers in C++, it is clear that the base class's access specification does affect the way the derived class inherits members of the base class. Therefore, the answer to the exercise is True.
