Class

Classes: A class is a abstract or user-defined data type, contrast to built-in fundamental types such as int or double . A class is represented as a three-compartment box:

• name,

• data members (or variables or attributes)

• member functions (or methods, or operations)

• The data member and member functions are collectively called class members.

• The syntax of defining a class consists of two sections:

  • class declaration
  • class implementation.

Class declaration is further divided into two sections: private and public. Class implementation contains member function definitions.

// Class Declaration Section - in Header file
class ClassName {
private:
   private-data-members
   private-member-functions
public:
   public-data-members
   public-member-functions
};  // Class declaration must end with a semi-colon
 
// Class Implementation Section - in the Implementation file
member-function-definitions
