Type System

C is a statically typed language, which means every object and function has a specific type that is known at compile-time, and the type of an object or function can not change.

The C type-system consists of the following types,

Signed Integer Types: signed char

short

int

long

long long

Unsigned Integer Types: unsigned char

unsigned short

unsigned int

unsigned long

unsigned long long

_Bool

Real Floating Types: float

double

Complex Types: float _Complex

double _Complex

long double _Complex

Special Types: void

char

Enumeration Types

Derived Types: Array Types

Function Types

Pointer Types

Structure Types

Union Types
