OOPs
●
OOPs revolves around Objects and Classes
●
Class may be seen as Structures+Functions
●
But it is much much more

●
Objects are INSTANCES of CLASSES

6.
Classes and Objects
Private, can be accessed only by
class functions.
Public, can be accessed thru objects
Object!
Accessing Object members

7.
OOPs
●
The 4 OOPs terms
●
Data Abstraction
●
Encapsulation
●
Inheritance
●
Polymorphism

8.
OOPs – Data Abstraction
●
Treat the class as a black box
●
Dont care what algorithm is used
●
Expose usable members as interfaces.

9.
OOPs – Data Abstraction

10.
OOPs – Encapsulation
●
All the attributes associated with a certain
object are “Encapsulated” in a Class.
●
Everything related to 1 kind of thing, in one
place.
●
Also used for Information Hiding

11.
OOPs – Encapsulation

12.
OOPs – Inheritance
●
More Generalization!
●
If there are 2 classes, create a new class
that has the INTERSECTION of the 2
classes' functionality.

13.
OOPs – Inheritance

14.
OOPs – Inheritance (Q)

15.
OOPs – Polymorphism
●
Same name – different functionality
●
Function Overloading is a TYPE of
polymorphism
●
Adhoc polymorphism is another (Operator
overload)
