Several types defined in Clause [input.output] are enumerated types.

Each enumerated type may be implemented as an enumeration or as a synonym for an enumeration.161

The enumerated type enumerated can be written:

enum enumerated { V $_{0}$ , V $_{1}$ , V $_{2}$ , V $_{3}$ , ..... };

inline const enumerated C $_{0}$ (V $_{0}$ );
inline const enumerated C $_{1}$ (V $_{1}$ );
inline const enumerated C $_{2}$ (V $_{2}$ );
inline const enumerated C $_{3}$ (V $_{3}$ );
  .....

Here, the names C

_{0}

, C

_{1}

, etc.

represent enumerated elements for this particular enumerated type.

All such elements have distinct values.
