Chapter 15: Problem 39

True or False The base class's access specification affects the way the derived class inherits members of the base class.

Short Answer

Expert verified
Answer: True

Step by step solution

01

Understand the base class's access specification

Access specifications are keywords in object-oriented programming languages, like C++ and Java, that determine the visibility of class members. There are three types of access specifications: 1. Public: Accessible to any part of the code. 2. Protected: Accessible to the class itself, its derived classes, and friends. 3. Private: Accessible only to the class itself and its friends.
02

Understand the inheritance process in derived classes

Inheritance is a process in object-oriented programming, where a class (derived class) can inherit members (properties and methods) from another class (base class). The derived class can perform all the functionalities of the base class and can also have its additional features. There are different types of inheritance: single, multiple, multilevel, hierarchical, and hybrid, but in all cases, the derived class inherits members from the base class.
03

Analyze the effect of access specification on inheritance

The access specification of the base class affects the inheritance process in the following ways: 1. If a member in the base class is declared as public, it will be accessible in the derived class and can be inherited. 2. If a member in the base class is declared as protected, it will be accessible only to the derived class (and other classes deriving from the derived class), but not to the rest of the code. 3. If a member in the base class is declared as private, it will not be accessible in the derived class, and therefore, it cannot be inherited.
04

Determine the truthfulness of the statement

Since the base class's access specification dictates the visibility of its members to the derived class, it directly affects whether these members can be inherited or not. Therefore, the statement is True. In conclusion, true or false: The base class's access specification affects the way the derived class inherits members of the base class. The answer is True.

A program has a class Potato, which is derived from the class vegetable, which is derived from the class Food. Is this an example of multiple inheritance? Why or why not?

Suppose a class named Tiger is derived from both the Felis class and the Carnivore class. Here is the first line of the Tiger class declaration: class Tiger : public Felis, public Carnivore Here is the function header for the Tiger constructor: Tiger(int x, int y) : Carnivore(x), Felis(y) Which base class constructor is called first, Carnivore or Felis?
