Advantages and Disadvantages of OOP

Why object-oriented programming required?

At the beginning of programming language were complex and though to use, not everyone could be a programmer. As they kept going on with their development and inventions, they unfolded new techniques and developed high level programming languages. The first high level programming language was developed by Konrad Zuse named Plankalkul. Then later FORTRAN (Formula Translation) came into being. It was available for everyone later. Then other languages like C and PASCAL came into being. All these languages are procedural programming languages. Understanding IT or its concepts is difficult for many students. Hence, in order to score better marks in IT related assignments you can take essay help and get better quality work done.

There is a huge difference in procedural procedures oriented programming Vs object-oriented programming. In procedural languages programs contains small parts called functions whereas, in OOP objects are used. Top down approach is followed in procedural programming language and bottom up approach is followed in OOP. In procedural programming operator or function overloading is not possible but it is possible in object-oriented programming (OOP). Procedural programming is less secure whereas OOP is more secure. Similarly, there were many other problems that procedural programming was not able to meet. This led to the development of Object-Oriented Programming (OOP).

Object Oriented Programming

In Object Oriented Programming also known as OOP in short, concepts of objects and classes came into existence. The whole program is written in a class, this class contained objects and various member functions. The first object-oriented programming language was Simula. The main reason behind the OOP is that we can use the real-world entities in our program. Some famous languages like C++, Java, PHP, C#, Python, etc. are Object oriented programming languages. OOP helps us apply real world entities like message passing, inheritance, polymorphism, objects, classes, abstraction, encapsulation, etc. in programming languages.

Advantages of Object-Oriented Programming (OOP)

Due to the various problems faced by the procedural languages, this concept was introduced. Therefore, it has a number of advantages over the procedural programming. OOP is still being widely used; new languages also adopt these OOP concepts. Let us discuss some the advantages of the Object-oriented programming:

1. Real Word Entities – In OOP real world entities are used. Classes and objects can be made of the things that are real and exist in the world. Example of real-world entities are pen, chair, student, hospital, etc. these examples can be considered as classes and their attributes will be considered as their object. Let’s discuss other example in order to better understand the classes and objects. Suppose, we take a student as class, then objects will be student name, roll number, section, address, mobile number, email, etc.

2. Code Reusability – Code reusability is one of the characteristics of object-oriented programming. The feature that explains this point is inheritance. In inheritance, the class and subclasses or parent and child classes can be derived and its data member and member functions can be used as such. This feature saves times and the user do not need to code again and again, if similar features or functionality is required. Long programs can be cut short and the lot of time can be saved.

3. Easy Management – code management becomes very easy in the object-oriented programming. As all the code is divided into a number of elements it becomes easy to manage. For instance, the whole program can be termed as a class and even if it contains a number of functions are written or coded in it, their objects can be made. This makes it easy to manage the code, as later you can initialize the object variable and make the function call.

4. Maintenance – Maintenance of code also becomes easy in object oriented programming. Because of easy management of the code maintenance also becomes easy. If the code is to be used by another programmer, still it will not create any ambiguity of correct guiding of coding is used.

5. Abstraction – In abstraction, only the useful data is visible to the user and not the things that they are not required to see. Abstraction is also called as data hiding. In order for you to understand let’s take an example – when you make your email id or login into an email id, you can only type the login Id and password and view it. You do not know how or cannot see how the data is being verified and how it is being stored? The user is always not aware about where their id and password are going? In which database? What is criteria for checking it? etc. Hence, it is very beneficial practice to use this feature as it provides data security.

6. Polymorphism – It is another feature of the object oriented programming. Polymorphism simply means that a function has many forms. Take example of your mother, she is one person but she has different roles to perform like being someone’s sister, wife, mother, aunt, employee, boos, etc. Similarly, even in the programming one function can be written, this function can be used in different forms depending on its arguments. It is called function overloading. Just like the functions even the operator can be overloaded. It is called operator overloading.

Disadvantages of Object Oriented Programming

Despite of having so many advantages it also has disadvantages.

1. Complex Design – Designing and proper implementation of Object Oriented Programming (OOP) concepts is complex and burdensome. Hence, it is difficult a many should have an extreme knowledge in order to design and implement OOPs concepts.

2. Many skills – A programmer required many skills for a better programming. Different skills like programming skills, designing skills, logical thinking and problem-solving skills are needed. If a programmer does not have an extreme knowledge about programming, then it becomes difficult for them to code and manage.

3. Large size & Many Instructions – Programs of object-oriented programming are of larger size in comparison with the traditional procedural programming. Due to the larger size of the program, many instructions are needed in order to execute the program. This make the code complex and lengthy.

4. Slow Speed – Due to large size of the programs its execution speed becomes slow. Even many coding instructions make the execution of the program slower and effects its efficiency.

These were some of the advantages and disadvantages of the Object-Oriented Programming Language and concepts. Coding and IT is not everyone’s cup of tea. Hence, it can be tedious task for some of the students to understand and work on their assignment. Luckily, if you to face this problem then you can take Assignment Help USA and complete your work in a better manner and in times.
