Polymorphism is the ability of one object to be treated and used like another object. Which reusability-related C++ OOPS feature do you use? The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. We use virtual functions to achieve Dynamic Binding. 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. Security is effected by preventing objects from obtaining references to other objects to which they should not have access. True/False 2)In UML the constraint denoted by "0..*" indicates what? Which feature of OOP indicates code reusability? Characteristics of an Object Oriented Programming language. What is abstraction with real time example? It cant be called as parent or instance of an object. Overall, using OOP provides for more reusable data structures and saves time in the long run. Today, well go through the fundamentals and features of OOPS so you can start using it in your projects. d) Basically all the features of OOP gets violated Which of the OOP features indicates code reusability? Which Feature of OOP illustrated the code reusability? This promise is predicated on the assertion that if you build generic objects they can be used and reused. The general reason why Java is considered to be more secure than, say C, is because it handles memory management for you. It is the process of creating a new Class, called the Derived Class, from the existing class, called the Base Class. That is is the wrong answer. b) The language should follow at least 1 feature of OOP Polymorphism As name suggests, Polymorphism means an ability to assume different forms at different places. 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. 2. Code for an extension. Q) What C++ oops feature has something to do with reusability? 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. 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. Q2: What is an object in OOPs?Ans:A class instance is referred to as an object. Simple classes are used to indicate complexity in abstraction. Which feature of OOP indicates code reusability? Which language does not support all 4 types of inheritance? With inheritance, an object can be extended and code from the parent object can be reused or overloaded in the child object. First of all, OOP way of code reuse is not the myth at all; the problem is different. 2. Inheritance means the use of code that is pre-written or created previously. Classes can be used to implement Abstraction in C. Using available access specifiers, class allows us to group data members and member functions. By doing this, we are reusing the fields and methods of the existing class. Abstraction is selecting data from a larger pool to show only relevant details of the object to the user. The term object in object-oriented programming refers to a specific instance of a class. Generics in Ada and classes in object-oriented languages promote code reuse. Which feature of the oops gives the concept of reusability? c) Operator Overriding Therefore, an instance of a class is known as an object. a) Encapsulation b) Inheritance c) Polymorphism d) Abstraction 6. Explanation: Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. Consider a family of three, consisting of the father, mother, and son. Inheritance. Create a function that will accept as arguments two integers and the name of the individual to some function void createContact that will be defined later (String name, int number1, int number2). It was designed to improve upon existing concepts in C. C# powers the Microsoft .NET framework alongside many web apps, games, desktop apps, and mobile apps. ___________ underlines the feature of Polymorphism in a class. The father makes the decision to teach his kid to shoot. a) Always true for any programming language B Polymorphism. How many basic features of OOP are required for a programming language to be purely OOP? Question 30, In the above diagram the relationship between person and employee can be best described as pick one its multiple choice ?? Abstraction is one of the key concepts of object-oriented programming (OOP) languages. Which header file is required in C++ to use OOP? The object-oriented programming approach allows developers to bind and manipulate data using exclusive functions.These functions cover a range of operations, including code reuse and variable designation. 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. 2003-2023 Chegg Inc. All rights reserved. Classes are easier to debug since they generally include all relevant information. Object-oriented programming (OOP) is defined as a basic programming paradigm that almost every developer has utilised at some point in their career. The following are the concepts in OOPs-Object; Class; Inheritance . View Answer, 3. The purpose of encapsulation and abstraction is to hide/group data into a single unit. Code reuse may imply the creation of a separately maintained version of the reusable assets. Answer. C is an object-oriented programming language that is not platform-dependent. Reusability is a desirable feature of a language as it. Q) Which C++ oops feature is related to re-usability? There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . A. Which of the following pairs are similar? 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. Its one of the most important OOP concepts. An object is not considered a standalone program; instead it is the service being used in the programs. Object-Oriented Programming (OOP) is a programming paradigm supported by several modern programming languages, including C++. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security. This makes programs more efficient and easier to understand. This mechanism actually inherits the fields and methods of the superclass. Abstraction, encapsulation, inheritance, and polymorphism are four of the main principles of object-oriented programming. Object-Oriented Programming or OOP is one of the most highly effective programming paradigms that revolve around objects or classes containing specified characteristics and behaviour. It doesnt support multiple inheritance. Question 38 (2 points) Which Feature of OOP boost the code reusability? We also have no idea how a bike works on the inside. a) Encapsulation. Click again to see term . View Answer, 12. Kindly, choose the right option for every question to check your final preparation. 15)ArrayList is a part of which of the following sub packages? If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? Although two methods or functions may have the same name, the number of arguments given into the method call may vary. Data abstraction is one of the most essential and important feature of object oriented programming in C++. 16. Some of the advantages of OOPS include Reusability, Data Redundancy, Code Maintenance, Security, Design Benefits, Easy Troubleshooting, Better Productivity, Polymorphism Flexibility, and Problem-solving. OOP promotes the reusability of code. Abstraction reveals just the most significant facts to the user while hiding the underlying intricacies. Code reuse is the practice of using existing code for a new function or software. With this type of programming, a program comprises objects that can interact with the user, other objects, or other programs. This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on OOP Features . Ethnicity, polymorphism, encapsulation, and abstraction are the four basic features. b) Inheritance. Which language does not allow you to inherit all four types of inheritance? Which among the following doesnt come under OOP concept? Why Do Cross Country Runners Have Skinny Legs? Because just the most necessary information is shown to the user, it helps to enhance the security of an application or software. Inheritance is the feature of OOPs that describes the reusability of code. Constructors in most object-oriented languages have the same name as the class and are public. 16. But we dont know internally what things are happening inside ATM machine when you insert an ATM card for performing any kind of operation. This article explains the fundamental concepts of OOP and its most significant advantages. When completing an object-oriented design, there are five basic concepts to understand: classes/objects, encapsulation/data hiding, inheritance, polymorphism, and interfaces/methods. View Answer, 5. Polymorphism is a fundamental concept of object-oriented programming. Which among the following, for a pure OOP language, is true? However, the advantages of object-oriented programming are many. b) May not be true with respect to all programming languages Reusability of the code can be achieved in CPP through inheritance. Object-oriented programming mainly focuses on objects that are . View Answer, 2. OOP provides benefits like code reuse, easy maintenance and also saves a lot of time and money. Which of the following syntax used to create an object of Class in Java? Answer: The 4 basic features are inheritance, polymorphism, encapsulation and abstraction. Do Men Still Wear Button Holes At Weddings? Code reuse is a general target of OOP and (theoretically) all the three pillars of OOP, namely Encapsulation, Inheritance and Polymorphism support it. Which C++ Oops feature is related to reusability? One of the most practical examples of encapsulation is a school bag. 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. a) Operator Overloading When it comes to solving the problem of code/data separation, the use of Object -Oriented Programming has played a big role in the rising of object reusability. Select one: a.Inheritance .xption c.Encapsulation d.Abstraction Objects.

We all use an ATM machine for cash withdrawal, money transfer, retrieve min-statement, etc in our daily life. Notify me of follow-up comments by email. Keep complicated information hidden from the user. Grasping OOP concepts is key to understanding how Java works. Member variables or instance variables facilitate a class instance to maintain its position. Question 38 (2 points) Which Feature of OOP boost the code reusability? For example, Sharon is a programmer who has developed an object for rendering . b) 6 2021. which feature of oops described the reusability of code. A site about programming languages, Technical topics And for codes too. Specifically, the right hand. It makes the code reusability and makes the file lighter in weight with less number of lines of source code. The father, on the other hand, is right-handed, while the kid is left-handed. Improve this answer. But that is not the topic of discussion. Further, one is, object use is must, secondly, message passing and lastly, Dynamic binding. d) Encapsulation and Inheritance Answer: (b). The in-depthtopic of Polymorphism will be discussed in later articles. Answer: The correct answer is Inheritance. LIVE Course for free. Share. 9) Which feature of OOPS described the reusability of code? Further, object use is required, message passing is required, and finally dynamic binding is required. The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. Conclusion. Objects are the basic run-time entities in an object-oriented system. Object-oriented programming (OOPs) is a programming paradigm that is based on the concept of objects rather than just functions and procedures. Object-oriented programming (OOP) is the most prevalent programming paradigm. Object-Oriented Security is the practice of using common object-oriented design patterns as a mechanism for access control. Polymorphism is to indicate different tasks performed by a single entity. Encapsulation is intrinsically linked to modularity. If you wish to learn the most in-demand Programming Languages to help you optimize your job opportunities check out the Programming courses from Intellipaat. Sort the Array in Ascending order (default). Encapsulation is one of the fundamentals of OOP (object-oriented programming). Which of the following is not a feature of pure OOP? 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. 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 feature of OOP indicates code reusability? Classes are commonly used to indicate large groupings with similar characteristics. Polymorphism is a feature of OOP that serves the purpose of OBJECT-ORIENTED PROGRAMMING OBJECT-ORIENTED PROGRAMMING PROMOTES MODULARITY AND REUSE It is often claimed that object-oriented programming is a better way of writing more modular programs leverages code sharing and design reuse minimises maintenance costs Thanks to its abstraction mechanisms 10. Option (b) is the correct answer to the question "Which feature of OOPS illustrated code reusability.". Observer b. Because Java compiles as bytecode which then runs inside a Virtual machine, it cannot access the computer it runs on like a natively compiled program can. It enables code reusability by allowing a new class. No, not by copying and then pasting the same code from one object-oriented programming. 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. Method overriding and method overloading are two ways that polymorphism enables the same method to perform various actions. This means we can add new features to an existing class without having to modify it. OOPs Concepts: 1 Class 2 Objects 3 Data Abstraction 4 Encapsulation 5 Inheritance 6 Polymorphism 7 Dynamic Binding 8 Message Passing It has a few logically different objects which communicate with each other according to the rules defined in the program. Which of the OOP features indicates code reusability? However, these features alone don't guarantee code reuse. These classes are further used for creating instances of the objects.
