Question

a) Dynamic or late binding is accomplished in C++ by using what kind of functions? [8] b) What sections of a parent class can a derived class access? c) What sections of a parent class can a derived class inherit? d) The word polymorphism means "many forms" - true or false? e) State one major difference between static and dynamic binding f) Lets suppose that we have a parent class named "A" and two derived classes "B" and "C". Let there be a display function for class "A" and class "B" but not for class "C". In my client code I make the following declarations: (1)A#x; (2) x - new B; (3) x->display0; (4) A*y; (5) y = new C; (6) y ->display0: i) Is (2) a correct assignment? ii) Which display function will be called in (3)? iii) Which display function will be called in (67

Explanation / Answer

Answer is as follows :

a) It can be done by virtual functions.

b) The derived class can access different methods or functions from the parent class.

c) The derived class inherits the public properties of parent class.

d) True, it derives from Poly + morphism from which poly means many and morphism means forms.

e) Dynamic Binding can be execute at run time and Static Binding execute at compile time.

f) Here we use the pointers to access methods from differen

i) Yes, Statement 2 is correct

ii) it will call display function of derived class B

iii) it will call display function of derived class C.
