Question 5.5. (TCO 4) What are a bass class and a derived class? How do you distinguish between a base class and its derived classes? What programming technique shall you follow when the implementation of a base class method does not appropriately describe the behavior of a derived class object? (Points : 18)

Question 6.6. (TCO 6) Distinguish between inheriting interface and inheriting implementation. How do inheritance hierarchies designed for inheriting interface differ from those designed for inheriting implementation? (Points : 18)

Question 7.7. (TCO 2) Define and implement the overloaded constructors that support the following test function for a Rectangle class. The data members for the Rectangle class are:

• length - integer number
• width - integer number

int main()
{ Rectangle r1(); //r1 will take all default value
Rectangle r2(4, 5); //r2 will take all supplied value
Rectangle r3(10); //r3 will take supplied length, width will take default value
Rectangle r4= r2; //r4 will take the same value of r2

//the rest of the code
}

Question 6.6. (TCO 6) Distinguish between inheriting interface and inheriting implementation. How do inheritance hierarchies designed for inheriting interface differ from those designed for inheriting implementation? (Points : 18)

Explanation / Answer

5.5Answer:class which is inherited known as base class.or super class.

class which does the inheriting is called subclass.

inheritance is the process of deriving a new class from an old one.the old class is known as super class.or base class.

6.6 Answer: A subclass is able to inherit "interface" or "implementation" from a super class.Inheritance heirarchies are designed for inheriting interface liable to contain functionalty gaint in heirarchy.Every new class inherits methods which are implemented in a super class ofetn hence the sub class utilizes the super class implementations.

Heirarchies designed to inherit the interface liable to contain their functionality lesser in heirarchy.A super class indicates one or more abstract methods which should declare to every concrete class in heirarchy and the seperate sub class override these methods to offer the sub class specific implementations.
