Data Types and Declarations
Type Specifiers
Type Specifiers
Type specifiers indicate the format of the storage associated with a given data object or the
return type of a function.
Syntax
type-specifier ::=
char
short
int
long
unsigned
signed
float
double
void
struct-or-union-specifier
enum-specifier
typedef-name
Description
Most of the type specifiers are single keywords. (Refer to chapter 9 for sizes of types.) The
syntax of the type specifiers permits more types than are actually allowed in the C
language. The various combinations of type specifiers that are allowed are shown in Table
3-1. Type specifiers that are equivalent appear together in a box. For example, specifying
unsigned is equivalent to unsigned int. Type specifiers may appear in any order,
possibly intermixed with other declaration specifiers.
