Refer limits.h for the details. It includes the limits..

#  define CHAR_BIT  8


#  define SCHAR_MIN (-128)
#  define SCHAR_MAX 127


#  define UCHAR_MAX 255


#  ifdef __CHAR_UNSIGNED__
#   define CHAR_MIN 0
#   define CHAR_MAX UCHAR_MAX
#  else
#   define CHAR_MIN SCHAR_MIN
#   define CHAR_MAX SCHAR_MAX
#  endif


#  define SHRT_MIN  (-32768)
#  define SHRT_MAX  32767


#  define USHRT_MAX 65535

......

#  if __WORDSIZE == 64
#   define ULONG_MAX    18446744073709551615UL
#  else
#   define ULONG_MAX    4294967295UL
