Introduction
• Computer Programming
The process of developing and implementing various sets of instructions
to enable a computer to do a certain task.
These instructions are considered computer programs and help the
computer to operate smoothly.
Introduction
• Procedural Programming Language
In Languages where programs are organized into blocks of code called
variously "subroutines", "functions", or "procedures", each of which
handles one particular task.
Procedural programming languages include
C, C++, Fortran, Pascal, and Basic.
• Non- Procedural Programming Language
Non-Procedural language that does not support "subroutines",
"functions", or "procedures"
Procedural programming languages include
Assembly language, Prolog.
Introduction
• Object-Oriented Programming(OOP)
Stands for "Object-Oriented Programming" OOP refers to a programming
methodology based on objects, instead of just functions and procedures.
These objects are organized into classes, which allow individual objects to
be group together.
Most modern programming languages including
C#, VB.Net, Java ,C++ and PHP etc.
Introduction
• Object
An object can be considered a "thing" that can perform a set
of related activities. The set of activities that the object performs defines
the object's behavior.
For example:
Student (object) can give the name or address.
• Class
A class is simply a representation of a type of object.
Class is composed of three things:
Name, Attributes, and Operations.
public class Student
{}
Introduction
• Encapsulation
• Inheritance
• Polymorphism
Introduction
• Encapsulation (or information hiding)
In Object Oriented Programming, encapsulation is an attribute of object
design. It means that all of the object's data is contained and hidden in the
object and access to it restricted to members of that class.
Introduction
• Inheritance
– Important concept in object-oriented
programming, it provides a way for objects to
define relationships with each other.
– Ability of a new class to be created, from an
existing class by extending it, is called inheritance.
public class Exception
{}
public class IOException : Exception
{}
Introduction
• Polymorphism
– Polymorphism is a generic term that means 'many shapes'.
More precisely Polymorphisms mean the ability to request that the
same operations be performed by a wide range of different types of
things.
– Polymorphism is achieved by using many different techniques named
method overloading, operator overloading and method overriding.
