type — Type specifiers
type-specifier ::= simple-type-specifier | class-specifier | enum-specifier | elaborated-type-specifier | cv-qualifier simple-type-specifier ::= [::] [nested-name ::] type-name | [::] nested-name :: template template-id | bool | char | double | float | int | long | short | signed | unsigned | void | wchar_t type-name ::= class-name | enum-name | typedef-name typedef-name ::= identifier elaborated-type-specifier ::= class-key [::] [nested-name ::] identifier | class-key [::] [nested-name ::] [template] template-id | enum [::] [nested-name ::] identifier | typename [::] nested-name :: identifier | typename [::] nested-name :: [template] template-id
Type specifiers are used throughout C++: in declarations, type
casts, new
expressions, and so on.
Although the syntax rules shown here are quite flexible, the semantic
rules impose many limits. For example, the simple syntax rules permit
short
long
as a type (specifically, as a decl-specifier-seq
; see
declaration), but that combination of type
specifiers is not permitted. See Chapter
2 for details about semantics for valid type specifiers.
