class class-name : inheritance-list {
  private-members-list;    
  protected:
  protected-members-list;
  public:
  public-members-list;
  } object-list;

The class keyword allows you to create new classes. class-name is the name of the class that you wish to create, and inheritance-list is an optional list of classes inherited by the new class. Members of the class are private by default, unless listed under either the protected or public labels. object-list can be used to immediately instantiate one or more instances of the class, and is also optional. For example:

   class Date {
     int Day;
     int Month;
     int Year;
   public:
     void display();
   };
