In object-oriented programming, a Class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods). 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). Class is a blueprint for the object. Objects are instances of a class. Class holds its own data member function, accessed and used by creating instance of that class. Object holds the data variables declared in a class and the member function work on these class objects.
