Object-oriented programming versus procedural programming

Programming is a vast field that is constantly evolving. Given the current technologies and frameworks, novices face a lot of skepticism and confusion. It is no secret that in order to become a successful programmer, no matter what language you choose, you must first learn the basics. One of these foundations is to understand the main patterns or models of programming and their differences. In this article, we take a look at object-oriented programming and the procedures and differences between the two.

Procedural programming

The programming model is a procedure derived from structured programming that uses selection, sequencing, and iteration. Procedural programming uses procedures to access a computer. These procedures can take the form of functions or routines or subroutines. Any program or any part of it can call these routines at runtime.

Procedural programming is also called “inline programming”, which uses a top-down method to execute instructions and solve problems. A simple program that calls for a number of routines for different operations follows a procedure structure.

Object-oriented programming

Object-oriented programming is an attractive programming model that uses the concept of objects. Instead of using logic and functions, this model organizes the software design around objects or data. As a result, developers can use object-oriented programming to change objects, not programming logic.

Complex and large programs are often designed as object-oriented programs; Because it dramatically improves reusability, efficiency, scalability and collaborative development. IOS and Android mobile applications are typically designed with object-oriented programming languages ​​such as Java. Object-oriented programming is based on the principles of abstract data, encapsulation, inheritance, and polymorphism.

Each object-oriented program has at least one class and objects that are actually called class instances. Each object has its own properties, and each class uses methods or functions that can be called on each object to perform a specific operation.

In the code below, you can see a simple object-oriented program of registered cars in a small town. Each car has characteristics such as manufacturer, model, color, engine capacity and registration number. In the example code above, the Cars class and each instance of this class has a unique set of attributes. Also, a method has been created that invokes updateRegistration methods to update the registration number of the vehicles sold.

The difference between object-oriented and procedural programming language

Now that we have an understanding of the two paradigms of object-oriented and procedural programming, let’s take a closer look at their differences. In procedural programming, the main program is divided into small sections called functions; In object-oriented programming, on the other hand, the program is divided into objects.

Object-oriented programming uses a bottom-up approach, unlike procedural programming. Another major difference is the use of access definitions in object-oriented applications. The access definition defines data against unauthorized access and is in fact an implementation of the principle of data encapsulation. Object-oriented programs are much safer because of the principles of abstraction and encapsulation.

Almost all programming languages ​​support artificial programming. Some of these languages ​​are: C-Fortran and Basic. Languages ​​such as C ++, Java, C # and Python are also popular object-oriented programming languages.

Understand the basics

Many novices today focus on popular frameworks such as Ricket or Node.js, ignoring key programming concepts such as data structures and object-oriented programming. In job interviews, questions are often asked, such as the concepts of basic programming, which can be problematic if you are unfamiliar with the basics of programming.
