Another use for enumerations is within class scope.
for instance
Got this from c++ primer plus 3rd editionCode:class Blueprint { private: const int Len=30; // error declaring a constant with class scope is an error because no object yet exists, until you create an object there is no place for the compiler to store a value. instead: class Blueprint { private: enum {Len=30};//class specific constant does not create a class data member
However that's abuse of enums. The correct way to do a class-scoped constant is to make it static:
Code:class HasConstant { public: static const int THE_CONSTANT; }; // Implementation file: const int HasConstant::THE_CONSTANT = 234;
All the buzzt!
