Question

In object-oriented programming, what is a class?

Answer 1

In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods).

The user-defined objects are created using the class keyword. The class is a blueprint that defines a nature of a future object. An instance is a specific object created from a particular class. Classes are used to create and manage new objects and support inheritance....a key ingredient in object-oriented programming and a mechanism of reusing code.

Answer 2

Basically, a class in Object-oriented programming is a blueprint of an object. You can think of it as a concept and the object is the embodiment of that concept. It is a set of instructions to build a particular type of object and will normally define how an object will behave and what it will contain when it is instantiated.
