Difference between POP and OOP

Home Articles Difference between POP and OOP

POP= Procedure-Oriented Programming

OOP= Object-Oriented Programming

For writing every program, there are two approaches. These are either following POP or OOP. You can choose either of the approaches for writing the program, but you would encounter a huge difference in their functionality and their opted approach. We are here to see the differences between the two. These have been evolved over time and are hugely different from each other. In the earlier times, there have been many inventions and developments for writing a program. But the problem was that not any of them was up to the mark and flawless. There were various methods involved in it. Some of them are-

  1. Modular Programming
  2. Top-Down Programming
  3. Bottom-Up Programming
  4. Structured Programming

Making programming efficient was the fundamental aim of all these methods. In the layman language, we need to make the process of making a program simpler as compared to the one already prevailing methods. Also, it needs to be bug-free and as well as ease in the understanding of the expansion and the modification of the codes.

The students need to think about the two approaches in simple words. Also, the differences between the two approaches are also required. Handling the development task of the moderately and complex program is one of the requirements of the programmers. This can be achieved with the help of the POP methods. But when the level of the complexity and the convolution increases, then programming in the procedure-oriented programming approach is hard. The types of the complexity get multifold and writing in that format following the POP methods is not efficient. It is because the number of bugs and the amount of time needed is high. So, the work of writing a program and that too free from bugs is hard. In addition to this, it takes a lot of time is needed to debug the program. This is definitely not effective.

Have you got a general idea of the difference between the two methodologies? You don’t have to follow the hard and the fast rule for the choice of the method for the development of a program. It is up to your choice and discretion. But most of the programmers pick the modern approach for writing a program because of the provided facilitated and the collaborative working.

The basic thing and the reason for the choice is the code reusability. In this, the users and the programmers can be picked by any number of programmers and that too for any number of times. This is the most prominent reason for the fast and effective development of the software.

Procedure Oriented Programming

Here, the keyword, ‘procedure’ is the main point or the point of focus. These include “a set of subroutines,” “a set of procedures,” “a set of functions.” C is the best and the widely known example of the procedure-oriented language. The presence of the functions in the C language is the key element. The functions and the subroutines are the prime areas which are to be emphasized for the given functions. These are the set of instructions for performing a particular task. There is a repetitive calling of the functions in the program for the execution of the tasks which they perform.

For instance, there is an involvement of the collection of the data by a program from the reader. These are accompanied by the performance of the calculations on the collected data. The list also includes the display of the users’ results for the request and the printing. The three functions support the major tasks of the program, which are reading, calculating and the printing of the program. All the different functions of the program perform the tasks separately.

The structures are the most important feature of the C language. A structure is used in the C language using the keyword “struct.” It is helpful in packing together the diverse types of data I to the single entity. Decimal point, integer data and the array data types are used in the structure. The reason for the wide acceptance and popularity of C language is the programming using structure. The computer program gets the real world requirements with the structure models. The main problem with the structures in C was that it could handle only data. Also, they do not allow the association of the data along with the data inside it. In addition to this, there was a need for the separated writing of the structures inside a program for the manipulation of the data members inside them.

Viewing the problem as the sequence of tasks is the method involved in POP. The sequence consists of reading, doing calculations and the display of the results. The first step is the analysis of the tasks, and then the development of the functions and the procedures for the implementation takes place in the program.

Object-Oriented Programming

The basic structure of the working and the functioning of the two approach differs. Retention of the basic features and the structures of the programs and their methods is the core of the object-oriented programming development. In this, there are several added concepts for the facilitation of the programming to be efficient. There are various applications of the OOP. Along with this, there are several and diverse features which come with the development of the OOP. These things have made the approach of the program possible in an entirely new way.

1. Data Hiding-
This is the first and the foremost feature which comes handy with the introduction of OOP in the programming world. Under this, the data gets a lot of significance. Using the methods of OOP, the programmer can hide any amount of data from the external world.

2. Basic feature in the POP= Class in OOP-
The class is a trait of the OOP used for packing together the different types of data in addition to the different functions. It is for the manipulation of the class data members. These can either be private or public.

3. Object-
It is one of the entities used in the OOP. These are used for the accessing of the functions and the data inside a class. The functions and the data in the class are called the class members.

4. Code Reusability-
Another important character of OOP is the reusability of the code. The feature or the property of inheritance is the reason for allowing the reusability of the code.

These are the basic differences in the two programming approaches for writing a program.
