Class: A class in C++ is the building block that leads to Object-Oriented programming. It is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A C++ class is like a blueprint for an object .

A class defines the structure and behaviors of all entities of a given type. An object is one particular “instance” of that type of entity . For example, if Dog is a class, then a particular dog named Lassie would be an object of type Dog.
