16.3 Method of description [description]

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

Each enumerated type may be implemented as an enumeration or as a synonym for an enumeration.130

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.

Such as an integer type, with constant integer values ([basic.fundamental]).
