Question Question 12
What are the differences between Procedural Programming and Object-oriented Programming?
| Procedural Programming | Object-Oriented Programming |
|---|---|
| Follows a top-down approach | Follows a bottom-up approach |
| Instruction Oriented | Data Oriented |
| The abstraction is at procedure (function) level. | The abstraction is at object (class) level. |
| The sequence of events in a large program is divided into functions. | Entire program is divided into objects. |
| Interaction with program is via direct function calls. | Interaction with program is via functions defined in the class only. |
| Real world is represented by 'procedures' operating on data. | Real world is represented by objects and the operations that can be performed on these objects. |
| Data and functions are separate. | Data and functions are encapsulated into a single unit. |
| Data security is less as it contains lesser features to protect the data. | It is more secure as one of its primary features include data hiding. |
| A function can access any other function's data by calling that function. | Only the data whose access has been granted can be accessed by another function. |
| Limited and difficult code reusability. | Versatile and easy code reusability. |
| Code is difficult to modify, extend and maintain. | Code is easy to modify, extend and maintain. |
| Some examples of Procedural Programming languages are C, COBOL, Pascal. | Some examples of Object Oriented languages are C++, Java, C#. |
