Explanation / Answer

Answers with explanations:

3.   (a) False //Derived class can access public member of base class
   (b) True    //Derived class can directly access public member of base class
   (c) False   //Derived class can change value of public member of base class but in its own class/scope
   (d) False   //Derived class cannot access private member of base class.

4.   (a) True    //It cannot initialize private memebers.
   (b) False   //It cannot initialize private memebers.
   (c) False   //It can initialize public members.
   (d) False   //private members are private to the class

5.   (b) A derived class can redefine any public member function of the base class
   //Public and protected member functions are only visible to the derived class.Hence derived class only redifine these functions.

6.   (c) Encapsulation

7. (a) B Class constructor first,A Class constructor second
   //First super class constructor is called then sub class constructor.

8.   (c) Mustang is an automobile
   //here automobile is a base class and Mustang is a derived class
   //Mustang has inherited all the properties of automobile like wheels,stearing etc.
