Differences between class and objects are as follows:
1) Class is a template of objects. An object is an instance of a class.
2) Class doesn't allocate memory when it is created but Object allocates memory when it is created.
3) Class is a logical entity but objects are physical entity.
4) Class is declared once on the other hand object is created many times as per requirement.
5) Classes cannot be manipulated as they are not available in the memory but objects can be manipulated.
A car is an example of a class because it contains instance variables and methods. It serves as the blueprint for other objects. As a result, car is a class.
However, its objects are Audi, Toyota, Nissan, Honda, and so on because they are made using the basic states of the car class and have car methods as well.
