Why Objects?
Procedural Languages
 Difference in Paradigm
 Modularity : Functions & Modules
 Data Undervalued
 Modeling of the real world
Why OOP?
Characteristics of OO
Languages
 Creating New Data Types
 Inheritance
 Polymorphism
 Dynamic Memory Allocation
Why C++?
Characteristics of C++
 Hybrid (Procedural + OO)
 Recursion
 Simple & Multiple Inheritance
 Polymorphism
 Association & Relationships
 Dynamic Behaviour
Strengths of C++
 Highly portable
 Fast (Strongly Typed)
 Power (of low & high level)
 Not forced OO Behaviour
OOP giveth
 Encapsulation
 Information Hiding
 Message Passing
 Late Binding : Dynamic Behaviour
 Delegation
 Generalization
 Polymorphism & Overloading
 Relationships
Benefits
 Modularity
 Maintainability
 Reusability
 Flexibility
I have a cat named Trash… if I were trying to
sell him (at least to a computer scientist), I
would not stress that he is gentle to humans
and is self-sufficient, living mostly on field
mice. Rather, I would argue that he is object-
oriented.
Roger King
My Cat is Object- Oriented
The Power is YOURS!!!
