Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. Older programming languages like COBOL and C followed the Procedural Programming approach. While working with procedural languages, it is not always clear which functions work on which variables but object-oriented programming provides you framework to place the data and the relevant functions together in the same object. This is the basic unit of object oriented programming. This tutorial demonstrated many of the techniques used in Object-Oriented programming: You used Abstraction when you kept many details private in each class. common for the application, and place them at a single place and reuse them An object is an entity or instance of a class. programming: Tip: The "Don't Repeat Yourself" (DRY) principle is about One of the most useful aspects of object-oriented programming is code reusability. The prime purpose of C++ programming was to add object orientation to the C programming language, which is in itself one of the most powerful programming languages.

object oriented programming tutorial

Read more... An object is an entity or instance of a class. Simula was the first object-oriented programming language. Object-oriented programming has several advantages over procedural programming: OOP is faster and easier to execute When the exiting operator or function is made to operate on new data type, it is said to be overloaded. Look at the following illustration to see the difference between class and Procedural programming is about writing procedures or methods that perform While designing C++ modules, we try to see whole world in the form of objects. There are some basic concepts of the Object Oriented Programming those are implemented by the Object Oriented Programming languages. The program written using these languages used to be a series of step by step instructions. For example, a person is an object which has certain properties such as height, gender, age, etc. Encapsulation provides security to the data. Read more... Encapsulation is the process of binding the data by making it private and functions to process that data into a single unit. The ability to use an operator or function in different ways in other words giving different meaning or functions to the operators or functions is called polymorphism. creating objects that contain both data and methods. Read more... Abstraction means hiding the implementation and showing only functionality to the user. Similar way, C++ classes provides different methods to the outside world without giving internal detail about those methods and data. the There are a few principle concepts that form the foundation of object-oriented programming −. The inheritance concept makes it possible to define subclasses of data objects that acquire or share base class characteristics. Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods. The concept of overloading is also a branch of polymorphism.

They made use of procedures/subroutines for making the program modular. The class concept not only reuse the code within the program in which it is written but also we can reuse the class members in another program, this will achieves reusability and modularity. As the name suggests Inheritance is the process of forming a new class from an existing class that is from the existing class called as base class, new class is formed called as derived class. The objects are mostly the physical entity but it can be a logical entity as well.

This characteristic of data hiding provides greater system security and avoids unintended data corruption. Read more... Inheritance is the process of acquiring or sharing the properties and behaviours of the base class into the sub class to achieve reusability.

An object of class creates the separate copies of the instance data members that means changing the values of a variable in an object will not change or reflect the values of variables in another object, so the code will not be able to accidentally access other program data. Basic concepts of Object Oriented Programming: Class in OOP - When you define a class, you define a blueprint for an object. You will learn much more about classes and objects in the next chapter. operations on the data, while object-oriented programming is about For example, a database system hides certain details of how data is stored and created and maintained. Java, Python, C++, Visual Basic .NET and Ruby are the most popular OOP languages today.

That is both data and function that operate on data are bundled as a unit called as object. Object-oriented programming has several advantages over procedural instead of repeating it.

Classes and objects are the two main aspects of object-oriented programming. code easier to maintain, modify and debug, OOP makes it possible to create full reusable The class is a model or blueprint or prototype of an object that defines or specifies all the properties... An Object in OOP -

Data abstraction refers to, providing only essential information to the outside world and hiding their background details, i.e., to represent the needed information in program without presenting the details. This programming paradigm focused on logic more than data and the program used to combine The object oriented programming considers data important rather than actions (functions). For example a car is an object which has certain properties such as color, number of doors, and the like.

This doesn't actually define any data, but it does define what the class name means, that is, what an object of the class will consist of and what operations can be performed on such an object.

Encapsulation is placing the data and the functions that work on that data in the same place. You should extract out the codes that are The core of the pure object-oriented programming is to create an object, in code, that has certain properties and methods. This is a very important concept of object-oriented programming since this feature helps to reduce the code size. That is both data and function that operate on data are bundled as a unit called as object. Poly refers to many. objects: So, a class is a template for objects, and an object is an instance of a class. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. The class is a model or blueprint or prototype of an object that defines or specifies all the properties of the objects. This property of OOP forces a more thorough data analysis, reduces development time, reusing the code and ensures more accurate coding. applications with less code and shorter development time. variables and methods from the class. While using W3Schools, you agree to have read and accepted our, OOP provides a clear structure for the programs, OOP helps to keep the C# code DRY "Don't Repeat Yourself", and makes Definition of Object Oriented Programming: The Object Oriented Programming ( OOPs ) can be defined as a programming model or paradigm that emphasizes or focus mainly on objects.
