Which feature of oops is described as the reusability of code? 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. We can solve real-world problems if we are using object-oriented programming. 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). d) Inheritance is a feature of OOP that allows a class to inherit the properties and methods of another class. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. A: Since OOP is one of the main development approaches which is easily accepted, the advantages are many. 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.

Explanation: The interaction between two object is called the message passing feature. Because Java has four OOPS concepts: inheritance, encapsulation, polymorphism, and abstraction. Modularity is linked to encapsulation; consider modularity as a method of mapping encapsulated abstractions to real, physical modules. For example, code inside the class template defines attributes and behaviors. c) Encapsulation only is violated b) Inheritance The object-oriented programming is basically a computer programming design philosophy or methodology that organizes/ models software design around data, or objects rather than functions and logic. Both procedural and object-oriented are imperative programming. Polymorphism is to indicate different tasks performed by a single entity. APIs provide a mechanism to enable code reuse. Inheritance is a virtue in object-oriented programming. Question 38 (2 points) Which Feature of OOP boost the code reusability? Which among the following, for a pure OOP language, is true?

Explanation: Java doesnt support all 4 types of inheritance. In C++ program if we implement class with private and public members then it is an example of data abstraction. The _destruct() method is optional, although it might be used to implement code that cleans up once an object is destroyed, such as shutting files or database connections. Encapsulation is the process of creating self-contained modules that connect processing processes to data. 23) also identifies another mechanism in object-oriented programming called inheritance, which he says is used to design two or more entities that are different but share many common features. 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. Write the Java code to display the content of the. To practice all areas of Object Oriented Programming (OOPs) using C++, here is complete set of 1000+ Multiple Choice Questions and Answers. Encapsulation and abstraction are meant to hide/group data into one element. A very common example of code reuse is the technique of using a software library. The fundamental purpose of OOP is to connect data and required functions so that no other section of the code may access them. This is the definition of abstraction. Abstraction is the concept of object-oriented programming that shows only essential attributes and hides unnecessary information. Polymorphism As name suggests, Polymorphism means an ability to assume different forms at different places. Object-oriented programming (OOP) is defined as a basic programming paradigm that almost every developer has utilised at some point in their career. It is the most popular methodology among developers. 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. d) 4 Inheritance. 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.

Data transfer is not a feature of OOP. 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. Characteristics of an Object Oriented Programming language. For example, say our object is an Employee. a) Data transfer Answer. View Answer, 4. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or super class 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. The ability to reuse existing objects is considered a major advantage of object technology. This OOPS feature inherits the features of another class in the programs. b) Inheritance. The purpose of encapsulation and abstraction is to hide/group data into a single unit. Object-oriented programming (OOP) is known as the most common programming paradigm. Modularity can be seen as a method of mapping encapsulated abstractions to real, physical modules with high cohesion within them and low inter-module interaction or coupling. A child class can access and use methods and fields of the parent class which leads to code reusability. 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. The answer to what in OOP produces code reusability is information hiding. 2022 - 2023 Times Mojo - All Rights Reserved Which feature of the oops gives the concept of reusability?
