Attempt All Questions. Each Question Carries 10 marks. Mention the references (if any) as footnotes or at the end after completing the question.
Q#1: Answer the questions related to the following code:
Class B
{
Public:
Void b1();
Protected:
Void b2();
};
Class A : public B
{
Public:
Void a1();
Protected:
Void a2();
};
Class C: public A
{
Public:
Void c1();
};
Void main ()
{
B temp1; A temp2; C temp3;
}

a) Name all member functions of all classes visible through temp1 in the main function?
b) Name all member functions of all classes visible through temp2 in the main function?
c) Name all member functions of all classes visible through temp3 in the main function?
d) Which class is the parent of class A?
e) Which class is the child of class A?

Q#5: What do you know about virtual function and pure virtual function? Differentiate the two with examples?
Solution#5 (to be typed here by the student)
• ANS
• A virtual which is a function that is defined in the base class .
It is preceded by the keyword “virtual” which tells the compiler to include dynamic binding in program.
• it must provide a definition in the class where it is declared.
• A pure virtual function is a function that is only declared in the base class.
• It dose not provide a definition. The class becomes an abstract class if it includes a pure virtual function.
Differentiate between virtual function and a pure virtual function
virtual function pure virtual function
• It contains a definition in the class which it is declared
• The function definition is overridden by the derived class.
• The class that contains a virtual function is not an abstract class.
• Object of the base class that contains a virtual function can be created as it is not an abstract class
• They do not help create interface classes.
