What is the difference between object oriented programming and procedural programming

In this kind of programming, objects can communicate as well as move with each other with the help of member functions. In object-oriented programming, the very first step is to collect all the objects for the manipulation by the programmer and identify the reaction between them is an exercise called data modeling.

The building blocks, or structure of object-oriented programming mainly consists of methods, classes, attributes, and objects. For a programmer, procedural programming might be the first programming paradigm to learn. Procedural code directly instructs a device in logical steps to finish a task. Procedural programming generally involves writing a list of instructions for a computer to tell what to do step by step to finish the task.

Most functions for sharing uses global data that can be accessed freely in the system from function to function. Based on the procedure call concept, the paradigm divides the program into procedures and are also known as functions or routines, which simply contain a series of steps to be carried out. Procedural programming uses a linear top-down approach and treats procedures and data as two different entities. C ommunication is done by return and parameter value in procedural programming.

The published circa were C and Pascal. OOP is said to be the most popular programming model among developers. It is well suited for programs that are large, complex, and actively updated or maintained. It makes the development and maintenance of software easy by providing major concepts such as abstraction, inheritance, polymorphism, and encapsulation.

These four are also the four pillars of an object-oriented programming system. OOPs, provide the ability to simulate real-world events much more effectively. We can provide the solution to real-world problems if we are using the Object-Oriented Programming language.

OOPs, provide data hiding, whereas, in Procedure-oriented programming language, global data can be accessed from anywhere. Now, let's see the comparison between Procedural programming and object-oriented programming. We are comparing both terms on the basis of some characteristics. The difference between both languages are tabulated as follows -. So, that's all about the article. Hope the article is informative and interesting to you, and you gain knowledge about procedural programming, object-oriented programming, and their comparison.

I will also discuss some important concepts that must be understood in using each language and how they compare to each other. After reviewing concepts I will discuss the design and development process for each language, followed by the advantages and disadvantages of each programming language.

Finally I will discuss the reusability and maintainability of each language, and how they differ from each other. Object-oriented Programming is a programming language that uses classes and objects to create models based on the real world environment.

An Object-oriented Programming application may use a collection of objects which will pass messages when called upon to request a specific service or information. Objects are able to pass, receive messages or process information in the form of data. One reason to use Object-oriented Programming is because it makes it easy to maintain and modify existing code as new objects are created inheriting characteristics from existing ones SEH, This cuts down the development time considerably and makes adjusting the program much simpler.

Another reason to use Object-oriented Programming is the ease of development and ability for other developers to understand the program after development. Well commented objects and classes can tell a developer the process that the developer of the program was trying to follow. It can also make additions to the program much easier for the new developer.

The last reason to use Object-oriented Programming that I will mention here is the efficiency of the language. Many programming languages using Object-oriented Programming will dump or destroy unused objects or classes freeing up system memory. By doing this the system can run the program faster and more effectively. Procedural Programming, which at times has been referred to as inline programming, takes a more top-down approach to programming.

Object-oriented Programming uses classes and objects, Procedural Programming takes on applications by solving problems from the top of the code down to the bottom. This happens when a program starts with a problem and then breaks that problem down into smaller sub-problems or sub-procedures. These sub-procedures are continually broken down in the process called functional decomposition until the sub-procedure is simple enough to be solved.

The issue that is obvious in Procedural Programming is that if an edit is needed to the program, the developer must edit every line of code that corresponds to the original change in the code. An example would be if at the beginning of a program a variable was set to equal the value of 1. If other sub-procedures of the program rely on that variable equaling 1 to function properly they will also need to be edited.

As more and more changes may be needed to the code, it becomes increasingly difficult to locate and edit all related elements in the program. A simple way to compare both programming methods is to think of Object-oriented Programming as learn to read picture book.

As children see pictures of simple objects like a house or picture they know that throughout the book when they see a picture of the house it represents the word house. The children can then read through the book as words are substituted throughout the story with pictures.

In Object-oriented Programming the classes could represent the pictures in the learn to read books. A house could represent a class and anything the developer wants to have included to describe that house like the color, size, number of bathrooms etc.

In Procedural Programming the learn to read book would be words on the page without pictures to help guide the young learner through the book. Notify me of followup comments via e-mail. Written by : jeyakanth. User assumes all risk of use, damage, or injury.

You agree that we have no liability for any damages. It is able to simulate the real world effectively. Data is active and the code is reusable. It is able to deploy better graphical user interfaces. OOP is based on a real time application whereas the entire focus of procedural programming is on data and functions. Procedural programming exposes the data to external entities thus compromising on security which is a strict no-no in the case of OOP.

In OOP, the programs are divided into objects, and the data is hidden from external entities. OOP has a major advantage over procedural programming when it comes to documentation of really long programs. Due to the organization and documentation, it is easier to keep track of the changes made in the code or for a new developer to understand the existing code.
