Q15: the head pointer points to NULL, it is an indication that a. the list is full and cannot accept any new nodes. b. the list has been destroyed c. the list needs to be destroyed d. there are no nodes in the list e. None of the above

Explanation / Answer

8-they both are able to have default arguments - this is wrong as destructors have no arguments.
9- possible with public functions and refrences as public functions of class B can access the private members of
the class and as the functions are public so it can be accessed outside the class.
10- class A can access private variables of class B.as class A is friend of class B so it can access all the private
members of the class.
11-Head pointer -
12-Static is not a kind of inheritance.
13-Automobile is the base class as others inherit the basic properties of the automobile class.
14-May include the statement template<typename Type> anywhere.
15-there are no nodes in the list .
