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.
