(15 marks) B5 a) Describe TWO features of object oriented programming languages that promote code reuse. 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.
Reusability - Wikipedia Chapter 4. Observer b. Polymorphism is a term used in software development to describe a variety of techniques employed by programmers to create flexible and reusable software components. But that is not the topic of discussion. Polymorphism.
Here, data and action can be redesigned and reused when required. Polymorphism is a feature of OOP that serves the purpose of indicating different tasks that are carried out a one entity. Methods and attributes only available from other methods in the same class make up the private/internal interface. Explanation: Java does not support all four types of inheritance. The correct answer to the question Which feature of OOP indicates code reusability is, option (B). Modularity ensures re-usability and thrives to minimize the duplication. 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. a) Inheritance Explanation: Inheritance indicates the code reusability. Objects are used in software development to combine data components with methods that alter them, allowing for the usage of abstract data structures.

For example, objects may override common parent behaviors with particular child behaviors through inheritance. Polymorphism As name suggests, Polymorphism means an ability to assume different forms at different places. Abstraction. Object-Oriented Programming or OOPs is a programming paradigm that revolves around the concept of object, which contains properties and methods. Which concept allows you to reuse the written code? d) Its vice-versa is true These concepts aim to implement real-world entities in programs. An object can be defined as an instance of a class, and there can be multiple instances of a class in a program. Which is not feature of OOP in general definitions? But we dont know internally what things are happening inside ATM machine when you insert an ATM card for performing any kind of operation. These concepts of sighting the OOPS features correspondence in I look at OOP as more of a way to interact with objects and abstract away the details of the data structure. Some features of Object Oriented programming are as follows: Emphasis on data rather than procedure; Programs are divided into Objects There are three major features in object-oriented programming that makes them different than non-OOP languages: encapsulation, inheritance and polymorphism. Polymorphism is an object-oriented programming language feature that allows a routine to use variables of various types at different times. It ensures code reusability. Today, we'll go through the fundamentals and features of OOPS so you can start using it in your projects. What are four basic principles of Object Oriented Programming? In 3 simple steps you can find your personalised career roadmap in Software development for FREE, Difference Between Product and Service Based Company. In same way, Abstraction represents only essential data to a user. Developing software that fulfills these requirements is a challenge. 47. The following are some of the advantages of encapsulation: Abstraction refers to the users interaction with just a subset of an objects characteristics and operations. c) Operator Overriding
Q5. There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . Which feature of oops is described as the reusability of code? A. Object-oriented programming (OOP) is the most prevalent programming paradigm. The ability to inherit the properties of one class to another, or inherit the properties from a base class to an inherited class is known as the concept of Inheritance. b) Polymorphism Object-oriented programming (OOP) is a software programming model constructed around objects. Overall, using OOP provides for more reusable data structures and saves time in the long run. So you are making use of already written the classes and further extending on that. Sanfoundry Global Education & Learning Series Object Oriented Programming (OOPs). Reusability of the code can be achieved in CPP through inheritance.
Which feature of OOP indicates code reusability? As a result, he brings him to the range with his favorite rifle and teaches him how to aim and fire at targets. Because a The features listed below are common among languages considered to be strongly class- and object-oriented (or The term is Greek and it loosely translates to "many forms". Abstraction using Classes: We can implement Abstraction in C++ using classes. In OOPS, what is the minimum functionality? In computer programming, Inheritance is an eminent concept in Object Orient Programming (OOPS) Paradigm. It is also taught as a conventional method to write for the most part of a programmers school career. inta public toata a) Error: same vanable name can be used twice b) Error Public must come first C) Error: data types are different for same variable d) It is correct 3.
What Is OOP (Object Oriented Programming)? - spiceworks.com Question 38: Answer: Inheritance Explanation: The reusability of code is possible using inheritance. Polymorphism is a term used to describe how a single entity . Which is not feature of OOP in general definitions? It cant be called as parent or instance of an object. Which Oops is accepted to reuse the code? These functions are specified inside the class and execute an action beneficial to that particular object type. Because there are 4 OOPS concepts in Java, and they are: Inheritance, Encapsulation, Polymorphism, And Abstraction. A variable, function, or data structure may all be considered an object. An object can be viewed as a real-world entity which has attributes and behaviour. c) Inheritance and polymorphism 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. c) The language must follow only 3 features of OOP We also have no idea how a bike works on the inside. It is one of the holy grails of modern software development. This concept is often used to hide the internal state representation of an object from the outside. Which two features of oops are the same?
OOPs MCQ & Online Quiz 2023 - OnlineInterviewQuestions This mechanism actually inherits the fields and methods of the superclass.
Understanding Code Reuse and Modularity in Python 3 - tutorialspoint.com a) Encapsulation b) Inheritance c) Abstraction d) Polymorphism View Answer. Which of the following is not a feature of pure OOP? 1. OOPs can be defined as: A modular approach where data and functions can be combined into a single unit known as an object. Object-oriented programming (OOP) is a way of thinking about and organizing code for maximum reusability. Code reusability is done using inheritance. Answer: b Explanation: Inheritance indicates the code reusability. Inheritance indicates code reusability, which is a feature of OOPS, whereas all other options do not represent OOPS features. 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.
Software Reuse and Object-Oriented Programming - SlideShare Object . Object-oriented programming (OOP) is a fundamental programming paradigm used by nearly every developer at some point in their career. All Rights Reserved. Further, it alsoresolves drawbacks of Procedural programming i.e code complexity, unusable code. This is what abstraction is. Inheritance is a feature by which a class acquires attributes of another class. Remove the business logic or main code away from any framework code. Static and Dynamic polymorphism ( Runtime Polymorphism ) . View Answer, 10. Object-Oriented programming focuses on binding attributes and behavior of a real-world entity represented using an object and supports features like abstraction, encapsulation, inheritance, and polymorphism. c) 5
What is Object-Oriented Programming (OOP)? - SearchAppArchitecture Polymorphism: An important feature of object-oriented programming that allows programmers to write programs that are easier for other projects to create and reuse. When a child class overrides a parent classs method, the child class might offer an alternative implementation. OOP promotes the reusability of code. It describes the idea of wrapping data and the methods that work on data within one unit, e.g., a class in Java. Object-oriented programming uses objects, but not all of the associated techniques and structures are supported directly in languages that claim to support OOP. Hence, it can be used to bundle the functions and data but not for code reusability. List types of behavior models. Continuing Laptops example, we can define multiple Laptop objects and each object would get the same attributes and behavior declared in the respective class. a) Code reusability b) Modularity c) Duplicate/Redundant data d) Efficient Code Answer: c Clarification: Duplicate/Redundant data is dependent on programmer and hence cant be guaranteed by OOP. Using the control Panel the home owner can interact with the Alarm, In a state diagram, the guard depends on the active state of the object. Object-Oriented Programming (OOP) is a programming concept in which a programmer uses classes and objects to implement real-world things in software development, such as inheritance, hiding, and polymorphism. Although two methods or functions may have the same name, the number of arguments given into the method call may vary. For a language to be classified as OOP, it must have these 4 OOP blocks. Object-oriented programming necessitates planning and thinking about the programs structure before starting to code and examining how to decompose the requirements into basic, reusable classes that you may utilize to create object instances. Tap card to see definition . a) Classes must be used Q1: Which are the best features of OOPs, and why explain?Ans: Encapsulation, inheritance, and polymorphism are three fundamental elements of object-oriented programming that distinguish it from non-OOP languages.
