In object oriented programming protected data members are accessible in the child and so we can say that yes inheritance promote software re-usability. OOP (object-oriented programming) is a programming paradigm that is completely based on ‘objects’. A good understanding of OOPs concepts can help in decision making when designing an application. Ad hoc code reuse has been practiced from the earliest days of programming.Programmers have always reused sections of code, templates, functions, and procedures. Object-oriented programming (OOP) is a fundamental programming paradigm used by nearly every developer at some point in their career. Everything in OOP is grouped as self sustainable "objects". Additional benefits of OOP include code reusability, scalability and In conventional function programming, the function sqrt(x) for different data types (x's type), will defined with different names, which takes a number as an input and returns its square root. How you should design an application and what language should be used. The organization of an object-oriented program also makes the method beneficial to collaborative development, where projects are divided into groups. This approach to programming is well-suited for programs that are large, complex and actively updated or maintained. And the complex, excessively long explanations in Wikipedia sometimes double the confusion. It stands for Object Oriented Programming. No, not by copying and then pasting the same code from one block to another and from there to another and so on. Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. Object-oriented programming is built around a number of concepts. Hence, you gain re-usability by means of four main object-oriented programming concepts. In object-oriented programming, the process of programming involves the following steps: Create classes for defining objects and their behaviors. In the class-based object-oriented programming paradigm, “object” refers to a particular instance of a class where the object can be a combination of variables, functions, and data structures. Blocks are a kind of measurement units like height, radius, and shape by default. In my opinion, this is a … Software reuse as a recognized area of study in software engineering, however, dates only from 1968 when Douglas McIlroy of Bell Laboratories proposed basing the software industry on reusable components. Object-Oriented Programming (OOP) uses a different set of programming languages than old procedural programming languages (C, Pascal, etc.). These words may sound scary for a junior developer. Procedural Programming takes a more top down approach to writing an application and while a developer who uses Object-oriented Programming to create applications would think of planning out the program with re-usable classes, a developer who uses Procedural Programming might plan out the program without the idea of recycling code. These concepts are implemented using classes, objects and methods, but it is useful to review those concepts more generally. Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. Inheritance helps in the software re-usability by using the existing components of the software to create new component. A general explanation of ‘object’ for better understanding – Mr. A is going to build a POT with the use of BLOCKS. Reusability In programming, reusable code is the use of similar code in multiple functions. Wikipedia defines OOP like this: "Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields (often known as attributes), and code, in the form of procedures (often known as methods)." The four principles of object-oriented programming are encapsulation, abstraction, inheritance, and polymorphism.
