<climits> (limits.h)

Sizes of integral types
This header defines constants with the limits of fundamental integral types for the specific system and compiler implementation used.

The limits for fundamental floating-point types are defined in <cfloat> (<float.h>).
The limits for width-specific integral types and other typedef types are defined in <cstdint> (<stdint.h>).

UCHAR_MAXMaximum value for an object of type unsigned char255 (28-1) or greater*
CHAR_MINMinimum value for an object of type chareither SCHAR_MIN or 0
CHAR_MAXMaximum value for an object of type chareither SCHAR_MAX or UCHAR_MAX
MB_LEN_MAXMaximum number of bytes in a multibyte character, for any locale1 or greater*
SHRT_MINMinimum value for an object of type short int-32767 (-215+1) or less*

ULONG_MAXMaximum value for an object of type unsigned long int4294967295 (232-1) or greater*
LLONG_MINMinimum value for an object of type long long int-9223372036854775807 (-263+1) or less*
LLONG_MAXMaximum value for an object of type long long int9223372036854775807 (263-1) or greater*
ULLONG_MAXMaximum value for an object of type unsigned long long int18446744073709551615 (264-1) or greater*

* the actual value depends on the particular system and library implementation, but shall reflect the limits of these types in the target platform.

Compatibility

LLONG_MIN, LLONG_MAX and ULLONG_MAX are defined for libraries complying with the C standard of 1999 or later (which only includes the C++ standard since 2011: C++11).
