What is the main difference between a class and an object?
Class Vs. Object
|A class is a logical entity||Object is a physical entity|

|You can declare class only once.||You can create more than one object using a class.|
What is a class and what is an object?
A class is a user-defined type that describes what a certain type of object will look like. A class description consists of a declaration and a definition.

What is the difference between classes and object instances?

When a class is declared, no memory is allocated but when the object of the class is declared, memory is allocated. So, class is just a template. An object can only be created if the class is already declared otherwise it is not possible
What is a class object?
In computer programming, the object class refers to a class created to group various objects which are instances of that class. Classes are code templates for creating objects. In cases where objects need to be grouped in a certain way, an object class is the “container” for a set of objects built on these templates.
