Is Object Oriented Programming the Same as Procedural?


Larry Thompson

Object Oriented Programming (OOP) and Procedural Programming are two distinct programming paradigms, each with its own set of principles and practices. While they share some similarities, it is important to understand that they are not the same. Let’s delve deeper into the differences between Object Oriented Programming and Procedural Programming.

Procedural Programming

Procedural programming is a linear approach to programming where a program is divided into a series of subroutines or procedures. These procedures are executed sequentially, following a specific order. The focus in procedural programming is on the process or procedure rather than on data.

In procedural programming, data and functions are separated. Data is typically stored in variables, which can be accessed and modified by any function within the program. Functions are used to manipulate this data by performing specific actions or calculations.


// Procedural Programming Example
int calculateRectangleArea(int length, int width) {
    return length * width;

int main() {
    int area = calculateRectangleArea(5, 3);
    printf("The area of the rectangle is: %d", area);
    return 0;

In this example, we have a procedural program that calculates the area of a rectangle. The calculateRectangleArea function takes the length and width as parameters and returns their product.

Object Oriented Programming

Object Oriented Programming (OOP), on the other hand, focuses on organizing data and functions into objects that interact with each other. It revolves around the concept of classes and objects.

A class is like a blueprint or template that defines the structure and behavior of an object. It encapsulates both data and functions that operate on that data. Objects are instances of classes, which can be created and manipulated during program execution.

OOP promotes the concepts of inheritance, polymorphism, and encapsulation. Inheritance allows objects to inherit properties and behaviors from parent classes.

Polymorphism enables objects to take on many forms and behave differently based on their class hierarchy. Encapsulation binds data and functions together, hiding the internal implementation details from external access.

// Object Oriented Programming Example
class Rectangle {
    private int length;
    private int width;

    public Rectangle(int length, int width) {
        this.length = length;
        this.width = width;

    public int calculateArea() {
        return length * width;

public class Main {
    public static void main(String[] args) {
        Rectangle rectangle = new Rectangle(5, 3);
        int area = rectangle.calculateArea();
        System.out.println("The area of the rectangle is: " + area);

In this example, we have an object-oriented program that calculates the area of a rectangle. The Rectangle class has private variables for length and width, a constructor to initialize these variables, and a calculateArea method to compute the area.

Differences Between OOP and Procedural Programming

Data Organization:

In procedural programming, data is typically stored in separate variables. In object-oriented programming, data is encapsulated within objects along with their corresponding methods.


Procedural programming focuses on procedures or functions that operate on data. Object-oriented programming focuses on objects that contain both data and methods.

Code Reusability:

OOP promotes code reusability through inheritance, allowing objects to inherit properties and behaviors from parent classes. Procedural programming does not have built-in mechanisms for code reuse.

Complexity Management:

OOP provides encapsulation, which helps manage program complexity by hiding implementation details. Procedural programming is more prone to code duplication and can become complex as the program grows larger.


OOP provides flexibility through polymorphism, allowing objects to take on different forms and exhibit different behaviors based on their class hierarchy. Procedural programming has limited flexibility as functions operate independently of each other.


In conclusion, Object Oriented Programming (OOP) and Procedural Programming are distinct programming paradigms with different approaches to organizing data and functions. OOP focuses on objects that encapsulate data and methods, while procedural programming emphasizes procedures or functions that operate on data. Understanding the differences between these two paradigms is crucial for choosing the most appropriate approach for a given problem.
