Static Data Members and ENUMS

• When a class contains an enum data member, and a public enum list, the enum data member may be assigned values within member functions by specifying the enumerated values. However, if the enum member is assigned values outside the scope of the class, the enumerated list values must be qualified by the class name and the scope resolution operator. Example...
• Static data members and member functions are shared by all objects of a class. In other words, static data and functions are not members of any instance, instead they belong to the entire class. This means that it is not necessary to instantiate an object in order to access a static data member of a class. Static data members must be initialized outside the class definition block and any other function block. Static member functions can only operate on static data members. A typical use of static methods is to implement a class-wide utility, and standard application of a static data member is to count the number of active objects of a class. Example...
