C++ class

An Object is an instance of a Class . When a class is defined, no memory is allocated but when it is instantiated (i.e. an object is created) memory is allocated. Defining Class and Declaring Objects. A class is defined in C++ using keyword class followed by the name of class.

Classes are user-defined data types that act as the blueprint for individual objects, attributes and methods. Objects are instances of a class created with specifically defined data . Objects can correspond to real-world objects or an abstract entity.

an object is an element (or instance) of a class ; objects have the behaviors of their class. The object is the actual component of programs, while the class specifies how instances are created and how they behave.

Object − Objects have states and behaviors. Example: A dog has states – color, name, breed as well as behaviors – wagging the tail, barking, eating. An object is an instance of a class. Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type support .
