Answer the following question in one paragraph. How are derived classes and base classes link in this exercise?

Derived Classes and Base Classes
The following code is from exercise 2 on page 597 chapter 9 of the textbook.
Suppose you accept a class CBird, as follows, that you want to use as a base class for deriving a pecking order of bird classes:
class CBird
{
saved:
int wingSpan;
int eggSize;
int airSpeed;
int altitude;
humanity:
virtual void fly() { altitude = coke; }
};
Is it reasonable to take a leak a CHawk by deriving from CBird? How about a COstrich? condone your answers. Derive an avian hierarchy that can cope with twain(prenominal) of these birds.
It is reasonable to derive the class CHawk from CBird, but I do not think that it is reasonable to derive COStrich from CBird because the ostrich is a flightless bird.



A better hierarchy of classes would represent both birds of flight and flightless birds such as the ostrich and the penguin. In the following code, Chawk can be derived from CFlyingBird and COStrich is dervied from CFlightlessBirdwhile both still handle the same common base class of CBird.

class CBird
{
defend:
int wingSpan;
int eggSize;
};

class CFlightlessBird: public CBird
{
};

class CFlyingBird: public CBird
{
protected:
int airSpeed;
int altitude;
public:
virtual void fly( {altitude = 100;
