What are classes and objects? How are they used in object-oriented programming?
What will be an ideal response?
An object is anything that can be seen, touched, or used. It is nearly any thing. A class is a pattern that the computer uses to create the object. Every object in an object-oriented program is created from a class. Each object is then referred to as an instance of the class. The class itself is not an object; only an instance of a class is an object.
