A.8 Declarations

Declarations specify the interpretation given to each identifier; they do not necessarily reserve storage associated with the identifier. Declarations that reserve storage are called definitions. Declarations have the form

• declaration:
  • declaration-specifiers init-declarator-listopt;

The declarators in the init-declarator list contain the identifiers being declared; the declaration-specifiers consist of a sequence of type and storage class specifiers.

• declaration-specifiers:
  • storage-class-specifier declaration-specifiersopt type-specifier declaration-specifiersopt type-qualifier declaration-specifiersopt
  init-declarator-list:
  • init-declarator init-declarator-list , init-declarator
  init-declarator:
  • declarator declarator = initializer

Declarators will be discussed later (Par.A.8.5); they contain the names being declared. A declaration must have at least one declarator, or its type specifier must declare a structure tag, a union tag, or the members of an enumeration; empty declarations are not permitted.
