which feature of oops described the reusability of code?

b) Inheritance a) Platform independent Inheritance. Answer: The 4 basic features are inheritance, polymorphism, encapsulation and abstraction. 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. 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. Option (b) is the correct answer to the question Which feature of OOPS illustrated code reusability.. d) Polymorphism. Explanation: Inheritance allows you to reuse your already written code by inheriting the properties of written code into other parts of the code, hence allowing you to reuse the already written code. For example, using inheritance you can use the code of the parent class in the child class and can eliminate the duplicate code. Object-oriented programming combines a group of variables (properties) and functions (methods) into a unit called an "object." The important features which are help to design the object-oriented programming and design is given below: Development over the designed programming paradigm. If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? Data Abstraction can be achieved in two ways: Abstraction using classes: An abstraction can be achieved using classes. (15 marks) B5 a) Describe TWO features of object oriented programming languages that promote code reuse. Which concept allows you to reuse the written code? Which language does not support all 4 types of inheritance? View the full answer. Which of the following is the feature of Object-Oriented Programming described the reusability of code? a) code reusability b) modularity c) duplicate/redundan Get the answers you need, now! For example, objects may override common parent behaviors with particular child behaviors through inheritance. With the help of a simple example, it may be comprehended in simple words. A Encapsulation. A major advantage of OOP is code reusability. A child class can access and use methods and fields of the parent class which leads to code reusability. Code reuse may imply the creation of a separately maintained version of the reusable assets. Objects are the basic run-time entities in an object-oriented system. An object-oriented programming is a way programming which enables programmers to think like they are working with real-life entities(a thing with distinct and Inheritance is a fundamental feature of an Object-Oriented programming. It refers to the bundling of data with the methods that operate on that data. in cpp, members of a class are ______ by default. Many latest languages are using OOPS concept as it is highly secure. The fundamental purpose of OOP is to connect data and required functions so that no other section of the code may access them. Share. The module name is generated out of the file name by removing the suffix ".py". Consider the application Polygon, which represents several Shapes. Hipparchus Hipparchus Between 162 and 127 BC, he was known to be a working astronomer. Hiding internal state and requiring all interaction to be performed through an object's methods is known as data encapsulation a fundamental principle of object-oriented programming. What are four basic principles of Object Oriented Programming? In computer programming, Inheritance is an eminent concept in Object Orient Programming (OOPS) Paradigm. Inheritance feature is used for concept of code re-usability as in inheritance a class can inherit properties and functions of existing well written class. a) Code reusability b) Modularity c) Duplicate/Redundant data d) Efficient Code View Answer Answer: c Explanation: Duplicate/Redundant data is dependent on programmer and hence cant be guaranteed by OOP. We use a library, saying reuse would sound dumb. A program written within the Object-Oriented Programming approach will have reusable blocks of codes termed classes. Abstraction is the concept of object-oriented programming that shows only essential attributes and hides unnecessary information. It is one of the holy grails of modern software development. The main users would be the accountant and the business manager. One of the most important and essential features of object-oriented programming in C is data abstraction. 1. The time effort of developers can also be reduced with inheritance, and it provides a better understanding of code to other developers as well, working in a team. These classes are further used for creating instances of the objects. Method overriding is used in runtime polymorphism. Q4. We also have no idea how a bike works on the inside. Examine how Polymorphism and the actual world are interconnected with examples. OOPs Interview Questions. The main principles of object-oriented programming are abstraction, encapsulation, inheritance, and polymorphism. In inheritance, there is a . Reduces the compilation time C. Lowers the maintenance cost D. Both A and C. View Answer (c) Reusability is the main feature It helps in reducing the complexity of writing very large codes as it provides the code reuse feature. The purpose of encapsulation and abstraction is to hide/group data into a single unit. 3. Unified Modeling Language. Polymorphism is to indicate different tasks performed by a single entity. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. It makes the code reusability and makes the file lighter in weight with less number of lines of source code. How To Reuse Code In Object-Oriented Programming. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security. This mechanism actually inherits the fields and methods of the superclass. The concept of inheritance in OOP promotes reusability. Answer: d. Inheritance. What is the correct syntax of inheritance? Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. From an object-oriented perspective, objects are the main building pieces of programs. To access a complicated item, abstraction uses simpler, high-level techniques. 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. Everything in OOP is grouped as self-sustainable objects. Polymorphism refers to the ability of any data to be processed in multiple ways. a) Encapsulation. The correct answer to the question Which feature of OOP indicates code reusability is, option (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. Objects are assumed, implemented or declared instances of various entities that contain code and data. Byte-code verifier checks the code fragments for illegal code that can violate access right to object. In OOPS, what is the minimum functionality? C++ also provide OOPS feature like encapsulation, abstraction, inheritance, and . Object oriented programming can be described as a programming model which is based upon the concept of objects. a) Encapsulation Most sensible languages allow writing of libraries, even C. Only we generally use the more sensible term "use". d) Encapsulation The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. 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. 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. Inside a class, encapsulation conceals the underlying software code implementation and the internal data of the objects. 11. a) Abstraction b) Encapsulation c) Polymorphism d) Inheritance* 10) Which operator from the following can be used to illustrate the feature of polymorphism? For a language to be classified as OOP, it must have these 4 OOP blocks. Method overriding is the term used in programming to describe this idea. . In Java, compilation is not included in the OOPS concept. Object-oriented programming languages include JavaScript, C++, Java, and Python, to name a few. Which is not feature of OOP in general definitions? Along with Abstraction, Encapsulation, and Polymorphism, Inheritance forms the backbone of Object-oriented programming and Java. Consider a family of three, consisting of the father, mother, and son. Removing access to parts of your code and making things private is exactly what Encapsulation is all about (often times, people refer to it Polymorphism and overloading: A. The son, on the other hand, was astute and chose to flip his fathers hands, putting his dominant hand on the trigger rather than the fathers. Encapsulation is the process of enclosing all critical information inside an object and only revealing a subset of it to the outside world. It lets us write generic code: which will work with a range of data, so we don't have to write basic stuff over and over again. Inheritance is the most essential feature of Object-oriented programming. c) Polymorphism Member variables or instance variables facilitate a class instance to maintain its position. So reusability is a must if you want an maintainable code. OOP is a striking shift from LP. If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? Simple classes are used to indicate complexity in abstraction. One of the most practical examples of encapsulation is a school bag. Security is effected by preventing objects from obtaining references to other objects to which they should not have access. Encapsulation keeps state private so that we can better enforce . But the multiple inheritance can be implemented using interfaces in Java. Because a polymorphic object can operate on a variety of values and types, it can also be used in a variety of programs, sometimes with little or no change by the programmer. Which of the following is not a feature of pure OOP? b) May not be true with respect to all programming languages Why Do Cross Country Runners Have Skinny Legs? a) The language should follow 3 or more features of OOP Rated by 1 million+ students . Select one: a.Inheritance .xption c.Encapsulation d.Abstraction Which OOPS concept is used as reuse mechanism? Inheritance is about code reuse, not hierarchies.
