Description
Various special symbols may accompany declarators. Parentheses change operator
precedence or specify functions. The asterisk specifies a pointer. Square brackets indicate
an array. The constant-expression specifies the size of an array.
A declarator specifies one identifier and may supply additional type information. When a
construction with the same form as the declarator appears in an expression, it yields an
entity of the indicated scope, storage class, and type.
If an identifier appears by itself as a declarator, it has the type indicated by the type
specifiers heading the declaration.
