OOP stands for Object-Oriented Programming.

Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions. Object oriented programming languages are various but the most popular ones are class-based.

Languages used in Procedural Programming:

FORTRAN, ALGOL, COBOL, 
BASIC, Pascal and C.

Languages used in Object Oriented Programming:

Java, C++, C#, Python, 
PHP, JavaScript, Ruby, Perl, 
Objective-C, Dart, Swift, Scala.

Example of simple procedural :

var a,b; 
function getSum(){ 
	return a+b; 
}

Example of object oriented language:

class sum{ 
	private var a,b; 
	function getSum(){ 
		return a+b; 
	} 
}

Object-oriented programming has several advantages over procedural programming:

  • OOP provides a clear structure for the programs
  • Program is divided into small parts called objects.
  • Improved software-development productivity
  • Improved software maintainability
  • Lower cost of development
  • OOP is faster and easier to execute
  • OOP follows bottom up approach intead of top down approach
  • OOP is based on real world
  • Adding new data and function is easy.
  • OOP has have access specifiers like private, public, protected etc.
  • OOP has concept of data hiding, Overloading, Encapsulation, polymorphism, Inheritance, abstract class.
  • OOP also has Reusability, dynamic nature ,inter communication within the blocks, multithreading, etc which are missing in procedural language.

What are Classes and Objects ?
There are two two main aspects of object-oriented programming, these are Class and object. The class is a template for the object, and the object is an instance of the class.
