Constant C and INT_MIN INT_MAX represent maximum, minimum integer limits.h defined in the header file.
INT_MIN defined in the standard header file in limits.h.
#define INT_MAX 2147483647
#define INT_MIN (-INT_MAX - 1)
Because 32-bit int occupies 4 bytes, the binary-coded according to the rules, INT_MAX = 2 ^ 31-1, INT_MIN = -2 ^ 31.C / C ++, all exceeds the limit, there will be an overflow occurs warning, but not appear and error. To integer exceeds this limit, you can use long long long integer 8 bytes 64.
Since the binary encoding the original code, rules and anti-complement arithmetic code of conduct, all programs for INT_MAX and INT_MIN operation should pay special attention, in times of overflow, do not follow mathematical rules.
INT_MAX + 1 = INT_MIN
INT_MIN - 1 = INT_MAX
abs(INT_MIN) = INT_MIN
More interesting is that, INT_MAX + 1 <INT_MAX, INT_MIN - 1> INT_MIN, abs (INT_MIN) <0.
