Chapter 15, Problem 15RQE

C++ Language Elements

Suppose that the classes Dog and Cat derive from Animal, which in turn derives from Creature. Suppose further that pDog, pCat, pAnimal, and pCreature are pointers to the respective classes. Suppose that Animal and Creature are both abstract classes.

15. Will the statement

Animal a;

compile?

CS 232 - Lab #6 - Pets Ahoy! We have recently been discussing the creation of classes in C++. Recall that classes serve as a "template" for the objects in our program, and that when we instantiate a class, we are creating an object which models the properties and behaviors of real-world objects. For this assignment, design and implement a parent class to represent a pet and several small sub-classes of the most common pets for cats, dogs, birds, and turtles. Each pet object is characterized by a type, name, birth date, owner, weight, sex, speak, and color. The variable data type for the type variable is a string that identifies the type of pet as a "dog", "cat", "bird", "turtle". The name is a string that identifies the name of the pet. The owner variable is a string that designates the name of the pet's owner. The weight specifies the pet's weight in pounds and is a double value. The speak variable is a string that holds an onomatopoeia of the sound the animal makes when it “speaks”…
Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', represents the side parallel to 'length'. 5. Create appropriate .h/.cpp files with constructors and destructors (wherever needed). which 6-
