CLASSES in C++

-
Classes are data structures clubbing together data and associated functions together.

Class declaration

FORMAT  :-

class  class_name
{


   access-specifier:

                             data and functions
 
   access-specifier:

                             data and function

                       ...
   
                       ...
  access-specifier:
 
                             data and function

} object-list;


C++ allows the declaration and definition of classes. Instances of classes are called object. In above declaration, class is a keyword. Access specifier may be public,private and protected, which decides scope and visibility of data members and member functions declared in the class definition . Thus class is said to be user-defined data type . So implementation of the same class varies from user to user. Following example illustrates the class definition including its members.
