Storage of basic types

The following table summarizes the storage associated with each basic type.

Sizes of fundamental types

Type Storage
char, unsigned char, signed char 1 byte
short, unsigned short 2 bytes
int, unsigned int 4 bytes
long, unsigned long 4 bytes
long long, unsigned long long 8 bytes
float 4 bytes
double 8 bytes
long double 8 bytes

The C data types fall into general categories. The integral types include int, char, short, long, and long long. These types can be qualified with signed or unsigned, and unsigned by itself can be used as shorthand for unsigned int. Enumeration types (enum) are also treated as integral types for most purposes. The floating types include float, double, and long double. The arithmetic types include all floating and integral types.
