Why object oriented programming is better than procedural?Asked by: Vergie Raynor

Security: Object-oriented programming is more secure than procedural programming, because of the level of abstraction or we can say data hiding property. It limits the access of data to the member functions of the same class. While there is no such data hiding in the procedural programming paradigm.View full answer
Correspondingly, Why Object-oriented programming is better than procedure oriented programming?
Object oriented programming provides data hiding so it is more secure. In procedural programming, overloading is not possible. ... In procedural programming, function is more important than data. In object oriented programming, data is more important than function.
Hereof, What are the advantages of OOP over procedural programming?.
- Modularity for easier troubleshooting. Something has gone wrong, and you have no idea where to look. ...
- Reuse of code through inheritance. ...
- Flexibility through polymorphism. ...
- Effective problem solving.
Subsequently, question is, Why do we prefer Object-oriented programming?
Object Oriented approach offers advantages like: Data Values are secured. Mishandling of data is protected. Error detection and correction becomes easier.
What are the advantages of object oriented design?
Advantages of Object Oriented Design:
Easier to maintain objects. Objects may be understood as stand-alone entities. Objects are appropriate reusable components. For some systems, there may be an obvious mapping from real entities to system objects.
That pretty much says it all. It's fine to reuse classes; in fact, it can be a major virtue of object-oriented programming. But don't take it to the extreme. Sometimes you're better off writing a new class instead of including masses of dependencies for the sake of DRY (don't repeat yourself).
- The program code is harder to write when Procedural Programming is employed.
- The Procedural code is often not reusable, which may pose the need to recreate the code if is needed to use in another application.
- Difficult to relate with real-world objects.
Benefits of OOP
OOP language allows to break the program into the bit-sized problems that can be solved easily (one object at a time). The new technology promises greater programmer productivity, better quality of software and lesser maintenance cost. OOP systems can be easily upgraded from small to large systems.
The main advantage of oop is data security. Data can be handled through the objects. The important features of oop like abstraction, encapsulation, polymorphism, inheritance are really helpful when we program for real world applications. The disadvantage is: It is difficult to understand for beginners.
Well Is Python an object oriented programming language? Yes, it is. With the exception of control flow, everything in Python is an object.
C is oriented to procedural, while C++ is oriented to objects, despite nearly identical core capabilities in that regard. Code that uses objects to implement designs that can only be done with objects (usually meaning taking advantage of polymorphism) is object oriented code.
C is an imperative procedural language. It was designed to be compiled to provide low-level access to memory and language constructs that map efficiently to machine instructions, all with minimal runtime support. Despite its low-level capabilities, the language was designed to encourage cross-platform programming.
- Re-usability: “Write once and use it multiple times” you can achieve this by using class.
- Redundancy: Inheritance is the good feature for data redundancy. ...
- Security: Using data hiding and abstraction only necessary data will be provided thus maintains the security of data.
- Size: ...
- Effort: ...
- It allows for parallel development. ...
- The modular classes are often reusable. ...
- The coding is easier to maintain. ...
- It can be inefficient. ...
- It can be too scalable. ...
- It can cause duplication.
- Data Abstraction and Encapsulation.
- Objects Can Encapsulate Operations Along with Data.
- Objects Are Efficient.
- Objects Can Represent Part-Whole Relationships.
For example, we can consider a car as a class that has characteristics like steering wheels, seats, brakes, etc. And its behavior is mobility. But we can say Honda City having a reg. number 4654 is an 'object' that belongs to the class 'car'.
Examples of Procedural languages: FORTRAN, COBOL, ALGOL, BASIC, C and Pascal.
The focus of procedural programming is to break down a programming task into a collection of variables, data structures, and subroutines, whereas in object-oriented programming it is to break down a programming task into objects that expose behavior (methods) and data (members or attributes) using interfaces.
The characteristics of procedural programming are: Procedural programming follows a top-down approach. The program is divided into blocks of codes called functions, where each function performs a specific task. Procedural programs model real-world processes as 'procedures' operating on 'data'.
No, object-oriented programming (OOP) is not dead. But it is significantly less ubiquitous than it used to be. ... It turned out that OOP was better suited to some problem domains than others. For example, OOP is still the most natural way of building user interfaces — windows and buttons.
Object Oriented programming has it's benefits. It creates reusable code that is patterned around well understood patterns. The advantage is that it's easier for a new developer who understands those patterns to work on existing code. It also allows pieces of one project to be used by other project.
As a beginner, OOP is also more difficult to read for several non-code related reasons. First, it's near impossible to understand why a piece of code exists if you're unfamiliar with the domain being modeled with classes. Secondly, OOP is a craft and is inherently opinionated.
There are many pitfalls in this category. Each one of the following can lead to poor hierarchy and class design, unpredictable behavior of objects, unnecessary complexity in the project, loss of OOD benefits, low rate of code reuse and product instability [Bosworth, 1992].
OOP requires a lot more memory allocations (MALLOC) and a lot more operations to run in memory than procedural code. It requires a lot more CPU time to perform its tasks. It is essentially 'overhead', wrapped around procedural code, adding to the CPU burden to execute it, especially when performing database operations.
