Declarations

Declarations in EEL associate a type with an identifier. The structure of EEL declarations mimics the recursive nature of EEL types.

A declaration is of the form:

declaration:
        type-specifier ;
        type-specifier declarator-list ;

declarator-list:
        declarator
        declarator , declarator-list

A type specifier names one of the basic types, a structure or union (described in Structures and Unions), or a typedef, a type abbreviation (described in Typedefs).

type-specifier:
        char
        short
        int
        struct struct-or-union-specifier
        union struct-or-union-specifier
        spot
        typedef-name

typedef-name:
        identifier

A declarator, on the other hand, specifies the relationship of the identifier being declared to the type named by the type specifier. If this is a recursive type, the relationship of the identifier's type to the basic type of the type specifier is indicated by the form of the declarator.

Declarators are of the following form:

declarator:
        identifier
        ( declarator )
        * declarator
        declarator [ constant-expression ]
        declarator [ ]
        declarator ()

If D is a declarator, then (D) is identical to D. Use parentheses to alter the binding of composed declarators. We discuss this more in Complex Declarators.
