This document outlines the syllabus for the CSE 219 Object Oriented Paradigm and Programming course taught by G.SasiKumar at VIT University. The course will use the textbook "Mastering C++" and will include homework, CAT exams, quizzes, presentations, and a final exam. Key topics will include an introduction to programming languages, object oriented programming concepts, advantages and applications of OOP.

4. Software
1. System software
2. Application software
System software: Directly interacts with the computer
system. Operating system, compiler, interpreter are
examples for this.
Application software: All the programs written by a
user with the help of any software is called as application
software.

5. Introduction to Programming
Languages
The shift in programming language is categorized as
following:
1. Monolithic Programming
2. Procedural Programming
3. Structural Programming
4. Object Oriented Programming
09/04/135 VIT - SCSE
7. Procedural Oriented Programming
Mainly comprises of algorithms.
FORTRAN and COBOL
The important features of Procedural Programming are
Emphasis is on doing things (algorithms)
Large programs are divided into smaller programs known as
functions.
Most of the functions share global data
Data move openly around the system from function to function
Functions transform data from one form to another
Employs top-down approach in program design
09/04/137 VIT - SCSE
8. Structured programming
Pascal and C
Structured programming is based upon the algorithm rather than
data
Programs are divided into individual modules that perform
different task.
Introduction of user defined data types
09/04/138 VIT - SCSE
9. Object Oriented Programming
C++, Smalltalk, Eiffel, Java, C# etc.
Object oriented programming is a programming
methodology that associates data structures with a set of
operators, which act upon it.
Depending on the object features supported, the languages are
classified into two categories:
Object-Based Programming Languages
Object-Oriented Programming Languages
09/04/139 VIT - SCSE
10. Object-based programming languages support encapsulation
and object identity without supporting inheritance, polymorphism
and message communications.
Example ADA.
Object – Based language = Encapsulation + Object Identity
Object-Oriented Programming Language incorporate all the
features of object-based programming languages along with
inheritance and polymorphism.
Object-oriented programming language = Object Based
Language + Polymorphism +Inheritance
09/04/1310 VIT - SCSE
11. Features of Object oriented Programming
Improvement of over the structured programming languages.
Emphasis on data rather than algorithm
Data is hidden and cannot be accessed by external functions
Objects may communicate with each other through functions
New data and functions can be easily added whenever
necessary
Follows bottom –up approach in program design
09/04/1311 VIT - SCSE
12. Basic concepts of object oriented
programming
Objects – data and function
Classes
Data Abstraction : the act of representing essential features
without including the background details or explanations.
Encapsulation – data and function into a single unit
Inheritance
Polymorphism
Message Passing : It is the process of invoking an operation
on an object.
Ex: ob.add(50);
09/04/1312 VIT - SCSE
13. Advantages of OOP
Through inheritance we can eliminate redundant
(Unnecessary) code and extend the use of existing classes.
The principle of data hiding helps for security.
It is possible to have multiple objects.
It is easy to partition the work in a project based on objects.
Object-oriented systems can be easily upgraded from small to
large systems.
Message passing techniques for communication between
objects
Code reuse is possible.
09/04/1313 VIT - SCSE
14. Applications of OOP
Real time systems
Simulation and modeling
Object oriented databases
Hypertext and hypermedia
AI and expert systems
Neural networks and parallel programming
Office automation systems
CIM / CAM / CAD systems
