(15 marks) B5 a) Describe TWO features of object oriented programming languages that promote code reuse. which feature of oops described the reusability of code? 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. Which of the following is not a feature of pure OOP? Answer. A: Since OOP is one of the main development approaches which is easily accepted, the advantages are many. OOps in java is to improve code readability and reusability by defining a Java program efficiently. Methods and attributes that are available from outside the class are known as the public / external interface. C Inheritance. 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. A prototype object serves as a base from which another object may derive its features and actions. However, the advantages of object-oriented programming are many. Object-Oriented Programming (OOP) is a programming model that uses classes and objects. Some people use . If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? 3. C. Inheritance boost the code reusability. Say we have a program. which oops concept offer maximum Code Reusability among - CodeProject 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. The father makes the decision to teach his kid to shoot. Question 38: Answer: Inheritance Explanation: The reusability of code is possible using inheritance.

B Polymorphism. If different properties and functions of a real world entity is grouped or embedded into a single element, what is it called in OOP language? We also have no idea how a bike works on the inside. 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. Tap card to see definition . a) Always true for any programming language Which feature of OOP indicates code reusability? With inheritance, an object can be extended and code from the parent object can be reused or overloaded in the child object. c) Abstraction Member variables or instance variables facilitate a class instance to maintain its position. A class is a generic template that you may use to create more specialized, concrete things. This OOPS feature inherits the features of another class in the programs. Polymorphism: An important feature of object-oriented programming that allows programmers to write programs that are easier for other projects to create and reuse. 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. We use a library, saying reuse would sound dumb. Developing software that fulfills these requirements is a challenge. As a result, he brings him to the range with his favorite rifle and teaches him how to aim and fire at targets. OOPs | Object Oriented Design - GeeksforGeeks So you are making use of already written the classes and further extending on that. By doing this, we are reusing the fields and methods of the existing class. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. 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. Answer: (c). d) Functions Overloading C++ also provide OOPS feature like encapsulation, abstraction, inheritance, and . A sign of good code reuse is that one can add a new feature to the code and minimally change the existing code; perhaps in one place or not at all. THE MAPPING It is observed that VHDL also corresponds to some features of Object Oriented Designs and Object Oriented Programming Structure (OOPS) like abstraction, encapsulation, reusability, polymorphism, concurrency etc. 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. This mechanism actually inherits the fields and methods of the superclass. These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. OOP is supported by C, but it is not a platform-dependent language. OOP is a striking shift from LP. Which Feature of OOP illustrated the code reusability?

Understanding Code Reuse and Modularity in Python 3 - tutorialspoint.com When a child class overrides a parent classs method, the child class might offer an alternative implementation. The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. The general reason why Java is considered to be more secure than, say C, is because it handles memory management for you. c) Abstraction. a) Nested class Hence, it can be used to bundle the functions and data but not for code reusability. A class defines ingredient members that allow its instances to have position and behavior. : A)binary association b) inheritance c) composition d) aggregation e ) none, 1)Multiplicity is the term used for measuring the number of attributes of a class. 1. Inside a class, encapsulation conceals the underlying software code implementation and the internal data of the objects. 1. The amount of net assets is exactly the same as a companys, Samsungs Program Dish Remote 20.0, 21.0, 20.1, or 21.1 have only eight codes in the 20.0 and 20.1 versions. Objects are the basic run-time entities in an object-oriented system. You can use it to reuse existing code, design clean APIs, and change the implementation of a class used in a composition without adapting any external clients. Explanation: Platform independence is not included in the OOPS concepts. Java programming is an object-oriented language that can be used to design the objects and to reuse the codes as and when required. Code reusability is done using inheritance. So reusability is a must if you want an maintainable code. 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. These four features are the main OOPs Concepts that you must learn to understand the Object Oriented Programming in Java. a) Inheritance The idea of write once, run many, also known as code reusability, is an important characteristic to the programming paradigm known as Object-Oriented Programming (OOP). b) Inheritance Both procedural and object-oriented are imperative programming. Inheritance is one of the crucial features of OOP, which strongly support "reusability". 5. for Reusability .cpp file is known as a source-code file Header files Separate files in which class definitions are placed Allow compiler to recognize the classes when used elsewhere Generally have .h filename extensions Driver files Program used to test software (such as Encapsulation is achieved when each object keeps its state private, inside a class. (10 marks) b) Name THREE different types of polymorphism commonly available in object oriented programming languages, giving code examples to support your answer. Constructors in most object-oriented languages have the same name as the class and are public. The in-depthtopic of Polymorphism will be discussed in later articles. Code reuse is the use of existing software to build new software. This feature is dependent on the programming language used. -only one allowed -maximum 10 -an optional, Explain how do behavior models differ from Scenario based models? b) Object must be used is violated Code duplication is avoided, and reusability is increased. Which is the correct syntax of inheritance? Tap card to see definition . View Answer. Polymorphism refers to the ability of any data to be processed in multiple ways. OOP promotes the reusability of code. Objects have their own properties and behavior. OOPs can be defined as: A modular approach where data and functions can be combined into a single unit known as an object. In C++ program if we implement class with private and public members then it is an example of data abstraction. It was created between 1961 and 1962 and published in his Sketchpad Thesis in 1963. Object-oriented programming mainly focuses on objects that are . Which OOPS concept is used as reuse mechanism? This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods). I know that schools ask questions like this and expect you to say inheritance. Object-Oriented Programming. View Answer, 11.

Hipparchus is regarded as the greatest ancient astronomical observer, as, Net assets are defined as an entitys total assets, minus its total liabilities. Object-Oriented Programming (OOP) is a programming paradigm supported by several modern programming languages, including C++. Further, one is, object use is must, secondly, message passing and lastly, Dynamic binding. (a) Polymorphism (b) Abstraction (c) Encapsulation (d) Inheritance. 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. These properties are put together within a single unit named class. Its utilized to break down a software program into reusable code blueprints (called classes) that you may use to build specific instances of things. OOP concepts (OOP) intend to improve code readability and reusability by defining how to structure a Java program efficiently. Code Reuse - an overview | ScienceDirect Topics Along with Abstraction, Encapsulation, and Polymorphism, Inheritance forms the backbone of Object-oriented programming and Java. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. As hardware and software became increasingly complex, manageability often became a concern. Inheritance is the most essential feature of Object-oriented programming. Object-Oriented Programming (OOP) was coined by Alan Kay circa 1966 or 1967 while he was at grad school.
