Classes are easier to debug since they generally include all relevant information. Object-oriented programming (OOP) refers to a programming methodology based on objects, instead of just functions and procedures as in functional programming. OOP features include the following: Encapsulation: This makes the program structure easier to manage . Encapsulation keeps state private so that we can better enforce . If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? d) Basically all the features of OOP gets violated 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. C is an object-oriented programming language that is not platform-dependent. Which feature of OOPS described the reusability of code? Which feature of OOP indicates code reusability? They are also known as the four pillars of OOPs. Inheritance: Inheritance is an important pillar of OOP(Object-Oriented Programming). Encapsulation refers to the creation of self-contained modules that bind processing functions to the data. Reusability could be described as creating a new class by reusing the properties of the existing class. This makes the code less redundant and more flexible to use in different classes. Because of their differing orientations, the father was concerned that he may not be able to teach his son how to shoot. A: Since OOP is one of the main development approaches which is easily accepted, the advantages are many. Both of the classes will be combined in the new class. With an object of a class, we can access the data members and member functions that can be accessed (as per the private, public, protected accessibility scope). Which language does not allow you to inherit all four types of inheritance? d) Message reading The data and methods are then enclosed in the object when it is created from the class. For example, we treat duck as an animal and not just as a duck. Explanation: Platform independence is not included in the OOPS concepts. Which is the correct syntax of inheritance? which feature of oops described the reusability of code? A class is like a blueprint for creating objects. Inheritance allows, code reusability and the polymorphism is, the occurrence of one function with different form. Encapsulation and abstraction are meant to hide/group data into one element. LIVE Course for free. Inheritance allows, code reusability and the polymorphism is, the occurrence of one function with different form. a) Polymorphism b). The following are the concepts in OOPs-Object; Class; Inheritance . d) Data hiding It cant be called as parent or instance of an object. In the early years of software development, it was common for a company to have to write all of the code for any application they produced.

View Answer, 4. If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? Objects contain data in the form of attributes and code in the form of methods. For example chair, bike, marker, pen, table, car, etc. Which language does not support all 4 types of inheritance? Encapsulation is not limited to OOP languages only. These properties are put together within a single unit named class. Encapsulation is intrinsically linked to modularity. c) Inline function Consider an object to be a sculpt of the real-world perceptions, processes, or objects that are important to the application youre designing. Which among the following, for a pure OOP language, is true? Of basic terms, Objects are the fundamental data types in object-oriented programming languages and are used to build object-oriented programming. View the full answer. 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. We also have no idea how a bike works on the inside. Which feature of oops is described as the reusability of code? It refers to the bundling of data with the methods that operate on that data. It doesnt support multiple inheritance. An object can be viewed as a real-world entity which has attributes and behaviour. Conclusion. View Answer, 9. Which feature of the oops gives the concept of reusability? Code reuse is the use of existing software to build new software. described here along with there mapped relevance with VHDL. Question 30, In the above diagram the relationship between person and employee can be best described as pick one its multiple choice ?? Code Refactoring; Object-Oriented Programming Standard Library; Article Versions. Which definition best describes an object? The answer to what in OOP produces code reusability is information hiding. Which feature of OOP indicates code reusability? A prototype object serves as a base from which another object may derive its features and actions. A class is Blueprint of an object which describes/ shows all the functions and data that are provided by an object of a specific class. Each kind of object is derived from a specific class of that type. Parent classes, in other words, extend properties and behaviors to child classes. b) Object must be used is violated a) Inheritance Explanation: Inheritance indicates the code reusability. Encapsulation and abstraction are meant to hide/group data into one element. Click card to see definition . Dynamic Binding which is also known as Late binding or run-time binding, is a process of executing the part of the code at runtime. Inheritance is relevant due to the concept of Code Reusability. Polymorphism is to indicate different tasks performed by a single entity. The father makes the decision to teach his kid to shoot. Code for an extension. Pure OOP can be implemented without using class in a program. Inheritance is the most essential feature of Object-oriented programming. Tap card to see definition . However, these features alone don't guarantee code reuse. Polymorphism is a fundamental concept of object-oriented programming. For example, a person, it can have attributes like name, age, gender and behaviour such as talking and walking. State True or False. Polymorphism is to indicate different tasks performed by a single entity. a) True In C++ program if we implement class with private and public members then it is an example of data abstraction. 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. Which among doesnt illustrates polymorphism? Data transfer is not a feature of OOP. a. Encapsulation. 2. 5. OOP promotes the reusability of code. In each application you create, you may employ a variety of objects of various sorts. It makes the data partitioned into two memory areas, i.e., data and functions, and helps make the code flexible and modular. But that is not the topic of discussion. It describes the idea of wrapping data and the methods that work on data within one unit, e.g., a class in Java. Which feature of OOP indicates code reusability? 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. 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. Unified Modeling Language. Explanation: The interaction between two object is called the message passing feature. That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity. What is reusability of code with example? The class that provides its attributes is known as the base class and the class that accepts those attributes is known as a derived class. It offers features like abstraction, encapsulation, modularity, inheritance, and polymorphism. Inheritance. b) False 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. Which feature of OOP indicates code reusability? This objective was achieved through the derivation of a taxonomy and a method that was applied to estimate indirect quality attributes such as understandability and maintainability. That is is the wrong answer. Answer: The correct answer is Inheritance. View Answer, 13. A program written within the Object-Oriented Programming approach will have reusable blocks of codes termed classes. Code reusability is one of the characteristics of object-oriented programming, which is done through the inheritance OOP concept. In OOP, an object is defined with its own properties. In programming languages, a polymorphic object is an entity, such as a variable or a procedure, that can hold or operate on values of differing types during the program's execution. The father, on the other hand, is right-handed, while the kid is left-handed.
