All objects are part of a class and share the common property and behaviour defined by the class in form of data members and member functions respectively. Many programming languages support object-oriented programming. You need to have a class before you can create an object. • In OOP (Object Oriented Programming) we encounter terms like "Encapsulation" and "Polymorphism ". Let us take a real-time application example. An object is a component of a program that knows how to perform certain actions and how to interact with other elements of the program.

In object-oriented terms, we say that your bicycle is an instance of the class of objects known as bicycles. In object-oriented terms, we say that the bicycle is an instance of the class of objects known as bicycles. Four core concepts of object-oriented programming are abstraction, encapsulation, inheritance and polymorphism. In object-oriented programming languages like C++, the data and functions (procedures to manipulate the data) are bundled together as a self-contained unit called an object. Object-Oriented Programming (OOP) is commonly used to develop software. Encapsulation is the hiding of internal mechanisms and data structures behind a defined interface. All employees receive 7% of the total sales. Sciences, Culinary Arts and Personal Methods are sometimes confused with functions, but they are distinct.
