Inheritance helps in the software re-usability by using the existing components of the software to create new component. 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. Additional benefits of OOP include code reusability, scalability and Object-oriented programming (OOP) is a fundamental programming paradigm used by nearly every developer at some point in their career. 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. A general explanation of ‘object’ for better understanding – Mr. A is going to build a POT with the use of BLOCKS. 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. It stands for Object Oriented Programming. These concepts are implemented using classes, objects and methods, but it is useful to review those concepts more generally. Hence, you gain re-usability by means of four main object-oriented programming concepts. The organization of an object-oriented program also makes the method beneficial to collaborative development, where projects are divided into groups. Object-Oriented Programming (OOP) uses a different set of programming languages than old procedural programming languages (C, Pascal, etc.). In object oriented programming protected data members are accessible in the child and so we can say that yes inheritance promote software re-usability. 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)." This approach to programming is well-suited for programs that are large, complex and actively updated or maintained. Blocks are a kind of measurement units like height, radius, and shape by default. 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 is built around a number of concepts. OOP (object-oriented programming) is a programming paradigm that is completely based on ‘objects’. 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. And the complex, excessively long explanations in Wikipedia sometimes double the confusion. The four principles of object-oriented programming are encapsulation, abstraction, inheritance, and polymorphism. Reusability In programming, reusable code is the use of similar code in multiple functions. These words may sound scary for a junior developer. In object-oriented programming, the process of programming involves the following steps: Create classes for defining objects and their behaviors. How you should design an application and what language should be used. Everything in OOP is grouped as self sustainable "objects". Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. 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. 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.
