Object-Oriented Programming (OOP) is a programming model that uses classes and objects. It makes the data partitioned into two memory areas, i.e., data and functions, and helps make the code flexible and modular. Polymorphism is the feature of OOPs that is illustrated by function overloading or method overloading. 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. Java does not support explicit pointer. d) Abstraction An object is referred to as a data field that has unique attributes and behavior.

Encapsulation is the process of creating self-contained modules that connect processing processes to data. View Answer, 12. Explanation: The interaction between two object is called the message passing feature. a) Encapsulation b) Polymorphism Encapsulation refers to the creation of self-contained modules that bind processing functions to the data. Abstraction reveals just the most significant facts to the user while hiding the underlying intricacies. Classes may also have functions known as methods that are exclusively accessible to objects of that kind. Polymorphism: An important feature of object-oriented programming that allows programmers to write programs that are easier for other projects to create and reuse. Methods and attributes only available from other methods in the same class make up the private/internal interface.

You may do this by storing the second number under the same name as the first. b) 6 Authors of new programs can use the code in a software library to perform these tasks, instead of re-inventing the wheel, by writing fully new code directly in a program to perform an operation. This isnt to say that OOP is the One True Way. 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. Encapsulation and abstraction are meant to hide/group data into one element. Does OOP provide better security than POP? For a language to be classified as OOP, it must have these 4 OOP blocks. Difference Between Inheritance and Polymorphism Importance on data rather than algorithms. Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. Because a The features listed below are common among languages considered to be strongly class- and object-oriented (or The term is Greek and it loosely translates to "many forms". For example, add(20,30) calls the two-parameter add() function, whereas add(10,20,30) calls the three-parameter add method. a) Encapsulation. The Object oriented programming makes it easier to the programmers to design and organize software programs. OOP concepts (OOP) intend to improve code readability and reusability by defining how to structure a Java program efficiently. Which among the following, for a pure OOP language, is true? Object-oriented programming necessitates planning and thinking about the programs structure before starting to code and examining how to decompose the requirements into basic, reusable classes that you may utilize to create object instances.
