Difference Between OOP and POP:
Each are programming processes whereas OOP stands for “Object Oriented Programming” and POP stands for “Process Oriented Programming”. Each are programming languages that use high-level programming to resolve an issue however utilizing totally different approaches. These approaches in technical phrases are often known as programming paradigms. A programmer can take totally different approaches to jot down a program as a result of there’s no direct method to resolve a specific downside. That is the place programming languages come to the image. A program makes it straightforward to resolve the issue utilizing simply the fitting method or you possibly can say ‘paradigm’. Object-oriented programming and procedure-oriented programming are two such paradigms.
What is Object Oriented Programming (OOP)?
OOP is a high-level programming language the place a program is split into small chunks known as objects utilizing the object-oriented mannequin, therefore the identify. This paradigm relies on objects and courses.
- Object – An object is principally a self-contained entity that accumulates each information and procedures to govern the information. Objects are merely situations of courses.
- Class – A category, in easy phrases, is a blueprint of an object which defines all of the widespread properties of a number of objects which can be related to it. A category can be utilized to outline a number of objects inside a program.
The OOP paradigm primarily eyes on the information moderately than the algorithm to create modules by dividing a program into information and features which can be bundled inside the objects. The modules can’t be modified when a brand new object is added limiting any non-member operate entry to the information. Strategies are the one solution to assess the information.

Objects can talk with one another via similar member features. This course of is named message passing. This anonymity among the many objects is what makes this system safe. A programmer can create a brand new object from the already present objects by taking most of its options thus making this system straightforward to implement and modify.
What is Process Oriented Programming (POP)?
POP follows a step-by-step method to interrupt down a process into a set of variables and routines (or subroutines) via a sequence of directions. Every step is carried out so as in a scientific method in order that a pc can perceive what to do. This system is split into small components known as features and then it follows a sequence of computational steps to be carried out so as.
It follows a top-down method to truly resolve an issue, therefore the identify. Procedures correspond to features and every operate has its personal function. Dividing this system into features is the important thing to procedural programming. So a lot of totally different features are written so as to accomplish the duties.
Initially, all the pc packages are procedural or let’s say, within the preliminary stage. So you could feed the pc with a set of directions on easy methods to transfer from one code to a different thereby engaging in the duty. As a lot of the features share international information, they transfer independently across the system from operate to operate, thus making this system weak. These primary flaws gave rise to the idea of object-oriented programming which is safer.
Main Differences between OOP and POP:
OOP stands for Object-oriented programming and is a programming method that focuses on information moderately than the algorithm, whereas POP, quick for Process-oriented programming, focuses on procedural abstractions.
In OOP, this system is split into small chunks known as objects that are situations of courses, whereas in POP, the primary program is split into small components based mostly on the features.
- Accessing Mode
Three accessing modes are utilized in OOP to entry attributes or features – ‘Non-public’, ‘Public’, and ‘Protected’. In POP, alternatively, no such accessing mode is required to entry attributes or features of a specific program.
The primary focus is on the information related to this system in case of OOP whereas POP depends on features or algorithms of this system.
In OOP, numerous features can work concurrently whereas POP follows a scientific step-by-step method to execute strategies and features.
- Information Management
In OOP, the information and features of an object act like a single entity so accessibility is restricted to the member features of the identical class. In POP, alternatively, information can transfer freely as a result of every operate accommodates totally different information.
OOP is safer than POP, because of the information hiding characteristic which limits the entry of knowledge to the member operate of the identical class, whereas there isn’t any such approach of knowledge hiding in POP, thus making it much less safe.
- Ease of Modification
New information objects may be created simply from present objects making object-oriented packages straightforward to change, whereas there’s no easy course of so as to add information in POP, at the least not with out revising the entire program.
- Course of
OOP follows a bottom-up method for designing a program, whereas POP takes a top-down method to design a program.
Generally used OOP languages are C++, Java, VB.NET, and so forth. Pascal and Fortran are utilized by POP.
OOP and POP Comparison Chart:
|OOP takes a bottom-up method in designing a program.||POP follows a top-down method.|
|Program is split into objects relying on the issue.||Program is split into small chunks based mostly on the features.|
|Every object controls its personal information.||Every operate accommodates totally different information.|
|Focuses on safety of the information no matter the algorithm.||Follows a scientific method to resolve the issue.|
|The primary precedence is information moderately than features in a program.||Capabilities are extra vital than information in a program.|
|The features of the objects are linked by way of message passing.||Different components of a program are interconnected by way of parameter passing.|
|Information hiding is feasible in OOP.||No straightforward approach for information hiding.|
|Inheritance is allowed in OOP.||No such idea of inheritance in POP.|
|Operator overloading is allowed.||Operator overloading shouldn’t be allowed.|
|C++, Java.||Pascal, Fortran.|
- A program is nothing however a set of step-by-step directions that solely a pc can perceive in order that it could provide you with an answer. There are totally different approaches to do this, which in technical time period, are known as programming paradigms.
- OOP and POP are such high-level programming paradigms that use totally different approaches to create a program to resolve a specific downside within the much less time doable.
- The concept is to resolve sophisticated duties utilizing programming with much less code. Whereas an object-oriented program relies upon primarily upon information moderately than the algorithm, a procedure-oriented program follows a step-by-step method to resolve an issue.
- OOP, in fact, has a bit edge over POP on many fronts akin to information safety, ease of use, accessibility, operator overloading, and extra.
