which feature of oops described the reusability of code?

Objects in object-oriented programming are answers to the idea of inheritance, resulting in improved program dependability, simpler software maintenance, library administration, and task division in programmer teams. Answer: (c). Encapsulation and abstraction are meant to hide/group data into one element. Polymorphism is to indicate different tasks performed by a single entity. Remove logic or main code away from any framework code:-. Polymorphism is a term used to describe how a single entity . Inheritance is a virtue in object-oriented programming. Object-oriented programming (OOPs) is a programming paradigm that is based on the concept of objects rather than just functions and procedures. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods). This mechanism actually inherits the fields and methods of the superclass. Because of their differing orientations, the father was concerned that he may not be able to teach his son how to shoot. Inheritance is about code reuse, not hierarchies. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.

True/False 2)In UML the constraint denoted by "0..*" indicates what? Modularity is the process of decomposing a problem (program) into a set of modules so as to reduce the overall complexity of the problem. Inheritance is the most essential feature of Object-oriented programming. This article will detail each of them. We can also control or check the data members and member functions to be accessed in the child classes by the means of access specifiers, types of inheritance, access specifiers, and their respective access will be discussed in later articles. Data transfer is not a feature of OOP. 1. Share. 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. 3 2022-02-15 11:56:58. Here, data and action can be redesigned and reused when required. Only the methods that are elements of a similar class only can access private members. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance. It's a site that collects all the most frequently asked questions and answers, so you don't have to spend hours on searching anywhere else.

Authors of new programs can use the code in a software library to perform these tasks, instead of re-inventing the wheel, by writing fully new code directly in a program to perform an operation. b) Data binding Object Oriented Programming (OOP) is based on the concept of objects rather than actions, and data rather than logic. Most sensible languages allow writing of libraries, even C. Only we generally use the more sensible term "use". A child class can access and use methods and fields of the parent class which leads to code reusability. Whereas LP has data structuresessentially variables that contain an arbitrary composition of native types such as float or integerOOP extends the data structure concept to describe a whole object.

Which of the following is the feature of Object-Oriented Programming described the reusability of code? An object represents a real-world entity, having a set of attributes and behavior. In other words, Inheritance self-implies inheriting or we can say acquiring something from others. Methods and attributes only available from other methods in the same class make up the private/internal interface. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function. c) Abstraction Answer. Code reusability, an important feature of Object-Oriented Programming (OOP), is enabled through inheritance, polymorphism, and information hiding. Take, for example, your mobile phone.

Answer (1 of 2): Probably the person asking this question wants to hear that it is a class inheritance or some other specific feature of object-oriented language the produces reused code. For example, using inheritance you can use the code of the parent class in the child class and can eliminate the duplicate code. Answer. Encapsulation can manage accessibility and hide the attributes and behaviour of an object. 5. So you are making use of already written the classes and further extending on that. Which feature of OOP indicates code reusability? Reusability in OOP is achieved by using C++ features that allow you to extend or reuse parent, super class, or base class properties in a subclass, as well as adding additional features or data members to the subclass, child class, or derived class. While code is the most common resource selected for reuse, other assets generated during the development cycle may offer opportunities for reuse: software components, test suites, designs, documentation, and so on. And that means it should be safe, secure, and reliable. Parent classes, in other words, extend properties and behaviors to child classes. (Multiple choice can be selected) A It is considered to be the blueprint of an object B The object that will be produced out of the said class will have the same fields/variables, functions/methods, and value C It has a special method called a constructor D It has a special variable called a constructor E None of the other choices are correct. Some of the advantages of OOPS include Reusability, Data Redundancy, Code Maintenance, Security, Design Benefits, Easy Troubleshooting, Better Productivity, Polymorphism Flexibility, and Problem-solving. b) False Most sensible languages allow writing of libraries, even C. Only we generally use the more sensible term "use". Which of the following is the feature of Object-Oriented Programming described the reusability of code? In OOP, an object is defined with its own properties. Answer. Continuing Laptops example, we can define multiple Laptop objects and each object would get the same attributes and behavior declared in the respective class.
