Which feature of OOP indicates code reusability? If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? It can be best explained with an example with a comparison to C language; in C language there was one limitation that we can not use the already used function name, but C++ provides us a new feature of Polymorphism, by which we can use the same function name again and again with different signatures. Sometimes we need to access some part at the runtime if we need then we can use this approach. Encapsulation. So reusability is a must if you want an maintainable code. As hardware and software became increasingly complex, manageability often became a concern. This concept is often used to hide the internal state representation of an object from the outside. The object-oriented programming is basically a computer programming design philosophy or methodology that organizes/ models software design around data, or objects rather than functions and logic. Reusability of the code can be achieved in CPP through inheritance. 11. The above code represents, how a laptops attributes and its behavior are put together in a single place. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. Code reuse is the practice of using existing code for a new function or software. Abstraction is the concept of object-oriented programming that shows only essential attributes and hides unnecessary information. This article explains the fundamental concepts of OOP and its most significant advantages. OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. Practice here the best OOPs MCQ Questions, that checks your basic knowledge of OOPs (Object Oriented Programming).This OOPs MCQ Test contains 25+ Best Multiple Choice Questions, that are very popular & asked various times in OOPs Exams/Interviews. OOPs MCQ (Multiple Choice Questions) - Javatpoint How To Reuse Code In Object-Oriented Programming - Loginworks Object-oriented programming (OOP) is the most prevalent programming paradigm. Programming Fundamentals: Reusability of Code Object-oriented programming and procedural programming are two programming paradigms. The concept of object-oriented programming models real-world entities very well. b) The language should follow at least 1 feature of OOP Code Reusability : The existing code in object oriented programming can be reused by the feature referred to as inheritance. Object can't be used with pointers because they belong to user defined class, and compiler can't decide the type of data may be used inside the class. Polymorphism is a feature of OOP that serves the purpose of indicating different tasks that are carried out a one entity. This makes the code less redundant and more flexible to use in different classes. Code reusability, an important feature of Object-Oriented Programming (OOP), is enabled through inheritance, polymorphism, and information hiding. Some features of Object Oriented programming are as follows: Emphasis on data rather than procedure; Programs are divided into Objects feature in object oriented programming languages . Object-oriented programming mainly focuses on objects that are . there is a class called "Control Panel". For example, MyCar and goldenRetriever are two particular instances of the abstract class. Polymorphism is the feature of OOPs that is illustrated by function overloading or method overloading. a) Inheritance Explanation: Inheritance indicates the code reusability. In procedural programming, a program is divided into various procedures or functions which operate on data, the issue with this approach is, when the program grows larger, the code redundancy, maintainability, and complexity increases. C# is an object oriented programming language designed by Microsoft. Because an object can only be associated with data in predefined classes or templates, the object can only "know" about the data it needs to know about. Next - Object Oriented Programming using C++ Questions and Answers - Classes. Object Oriented Programming Objective type Questions and Answers. In each application you create, you may employ a variety of objects of various sorts. b) May not be true with respect to all programming languages Object-Oriented Programming. Of basic terms, Objects are the fundamental data types in object-oriented programming languages and are used to build object-oriented programming. Object-oriented programming (OOP) is defined as a programming paradigm (and not a specific language) built on the concept of objects, i.e., a set of data contained in fields, and code, indicating procedures - instead of the usual logic-based system. c) Abstraction These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. Objects have their own properties and behavior. Object-Oriented Programming (OOP) is a programming paradigm supported by several modern programming languages, including C++. So, the object manages its own state via methods and no other class can touch it unle Using inheritance, we can create a general class that defines traits common to a set of related items. Programming Fundamentals: Reusability of Code Essay Example. A class is like a blueprint for creating objects. Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. Which language does not support all 4 types of inheritance?

Should You Learn Object-Oriented Programming Languages? feature in object oriented programming languages . protected (or class-protected) specifies enables the class itself and all classes under it (sub-classes) to access the member and public means that member can be accessed by its name using any code. A class defines ingredient members that allow its instances to have position and behavior. The term encapsulation (or OOP Encapsulation) is used in object-oriented computer programming languages to refer to the bundling of data and the methods that operate on it into a single unit.

OOP provides benefits like code reuse, easy maintenance and also saves a lot of time and money. Most sensible languages allow writing of libraries, even C. Only we generally use the more sensible term "use". Which Feature of OOP illustrated the code reusability? Classes can be used to implement Abstraction in C.
