type | the underlying type for T |
[edit] Notes
Each enumeration type has an underlying type, which can be
1. Specified explicitly (both scoped and unscoped enumerations)
2. Omitted, in which case it is int for scoped enumerations or an implementation-defined integral type capable of representing all values of the enum (for unscoped enumerations)
