Class & Object

Class:

• Blue Print (set of instruction to build a specific type of object) or prototype that defines the variables and the methods (functions) common to all objects of a certain kind.
• Class is just logical representation.
• Not stored in any memory.

Object

• Instance of class.
• Physical representation of the class.
• Block of memory that has been allocated.
• Stored in memory (i.e variables present in class).
• Helps us to access the member of a class or struct either they can be fields, methods or properties
• A program may create many objects of the same class.
• Consists of methods and properties to make a particular type of data useful

Class Vs Object

• Class is a template from which objects are created.
• Object determines the behavior of the class.
• Class is an entity that determines how an object will behave and what the object will contain.
