              header

              <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>).

              * 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).
