Difference Between OOPs and POPs [OOP Vs POP]

The POP or procedural programming language came before the OOP or object-oriented programming. The focus on OOP is data and security and real-world object programming whereas the focus of POP was the approach to solving the problem in a systematic manner. The POP came after the assembly language and was focused on the development of application software but later when business required security and data abstraction than OOP concept was introduced to make the code more usable and also provided more security and functionality than POP to deal with the real-life scenario where data sent from one program to other and the company have to keep their code hidden. 

Difference Between OOPs and POPs

OOP stands for object-oriented programming POP stands for procedural oriented programming
OOP is more real-world oriented programming as use the objects and its function that are similar in the real world POP is more getting things done programming it existed before the OOP to get the task done on machines
The programs use various objects and classes The programs use various functions and iterations
Object-oriented programming uses a bottom-up approach. The classes are initiated when they are called by the main program. Procedural oriented programming uses a top-down approach. The program is divided into functions and they perform various tasks.
The data is stored as local values in classes and cannot be accessed by outside functions The data is stored as global values and therefore can be accessed by any function
There is more code reusability that is achieved with classes and objects. This leads to shorter programs that are easy to read and debug There is less code reusability that is achieved via function calls only. This leads to lengthy programs and hard to read and debug.
The functions of the object are linked with the help of message parsing The functions of the programs are interconnected to each other with help of parameter parsing
In OOP, the objects can move and communicate with the help of member function In POP, the data can move freely from one function to another within the program
The OOP gives more importance to data than functions for execution The POP gives more importance functions rather than data for execution
In OOP, the data is protected in the classes with the help of an access modifier in which the data can be private or public. In POP, the data is opened to all the functions it does have a local variable but this not prevent to access from the main function
In OOP, the functions and data can easily be added by adding them to their respective classes In POP, to add function and data who have to write more code than OOP and take care of variables and function names
In OOP there exists a concept of data abstraction which helps the programmer to specify the data to be viewed In POP there exists no method to hide the data or the code from the programmer or user
OOP supports data overloading which means the same function can support different parameters or multiple functions can support the same name POP does not support data overloading
OOP support Inheritance which means functions can be reused from one class to another POP does not support inheritance there is no concept to reuse the function
Security of the data is focused more than to solve the problem Less focus on security and more focus on the approach to solving the problem
Examples of OOP include C++, JAVA, PHP, etc. Examples of POP include FORTRAN, Basic, COBOL, C, etc.
