•Difference between OOP vs. POP.
What is procedural oriented programming?
•computer programming language that specifies a series of well-
structured steps and procedures within its programming context to
compose a program.
•It contains a systematic order of statements, functions and
commands to complete a computational task or program.
• In the procedure oriented approach, the problem is viewed as
a sequence of things to be done such as reading, calculating and
Some characteristics of Procedure Oriented
•Large programs are divided into smaller programs known
•Most of the functions share
•Data can easily flow from
one function to another.
•Functions transform data from one form to another.
•Employs top-down approach in program design.
Advantages of procedural oriented programming:
•Allows quick completion. It is faster than oop.
•It is good for general purpose programming.
•It has portable source code-use different compiler to target
•Large reference is available on well-tired tested algorithms
No need to reinvent the wheel.
•Requires less memory space.
Disadvantages of procedural oriented programming:
•It is difficult to relate with the real world objects.
•The codes are difficult to maintain, if code grow large.
•It does not have automatic memory management like java.
•There is no security of data.
•Difficult to modify old codes.
•There are no access specifies.
What Object-Oriented Programming?
• Object-oriented programming is centred on
creating objects rather than procedures/
• Objects are a melding of data and procedures
that manipulate that data.
• Data in an object are known as attributes.
• Procedures/functions in an object are known
• Basic Principles of Object Orientation
• Interface and Abstract Class
Concepts of object oriented programming:
• Informally, an object represents an entity, either physical,
conceptual, or software.
– Physical entity
– Conceptual entity
– Software entity
• The state of an object normally changes over time.

• Behavior determines how an object acts and reacts.
• The visible behavior of an object is modeled by the set of
messages it can respond to (operations the object can perform).

Modularity is a fundamental aspect of all
successful large programs.
Emphasizes relevant characteristics.
Suppresses other characteristics
• Encapsulation means to design, produce, and
describe software so that it can be easily used
without knowing the details of how it works.
• Also known as information hiding
Implementation details which
are invisible for client
Information which can’t be
accessed by client
• Inheritance —a way of organizing classes
• Term comes from inheritance of traits like eye color, hair color,
and so on.
• Classes with properties in common can be grouped so that
their common properties are only defined once.
• Is an “is a kind of” relationship

•The word polymorphism comes from Greek and means having
several different forms. This is one of the essential concepts of
• Where inheritance is related to classes and (their hierarchy),
polymorphism is related to object methods.
•Types of polymorphism :
Advantages of Object-Oriented languages
•Ease of management.
•Improved software-development productivity.
•Improved software maintainability.
•Lower cost of development.
•The disadvantages of Object-Oriented
•Programs that are built using this language tend to take
longer to initially create.
