The limits for integer types are listed in the following table. These limits are also defined in the standard header file <limits.h>.
| Constant | Meaning | Value |
|---|---|---|
| CHAR_BIT | Number of bits in the smallest variable that is not a bit field. | 8 |
| SCHAR_MIN | Minimum value for a variable of type signed char. | -128 |
| SCHAR_MAX | Maximum value for a variable of type signed char. | 127 |
| UCHAR_MAX | Maximum value for a variable of type unsigned char. | 255 (0xff) |
| CHAR_MIN | Minimum value for a variable of type char. | -128; 0 if /J option used |
| CHAR_MAX | Maximum value for a variable of type char. | 127; 255 if /J option used |
| MB_LEN_MAX | Maximum number of bytes in a multicharacter constant. | 5 |
| SHRT_MIN | Minimum value for a variable of type short. | -32768 |
| SHRT_MAX | Maximum value for a variable of type short. | 32767 |
| USHRT_MAX | Maximum value for a variable of type unsigned short. | 65535 (0xffff) |
| INT_MIN | Minimum value for a variable of type int. | -2147483648 |
| INT_MAX | Maximum value for a variable of type int. | 2147483647 |
| UINT_MAX | Maximum value for a variable of type unsigned int. | 4294967295 (0xffffffff) |
| LONG_MIN | Minimum value for a variable of type long. | -2147483648 |
| LONG_MAX | Maximum value for a variable of type long. | 2147483647 |
| ULONG_MAX | Maximum value for a variable of type unsigned long. | 4294967295 (0xffffffff) |
| LLONG_MIN | Minimum value for a variable of type long long | -9223372036854775808 |
| LLONG_MAX | Maximum value for a variable of type long long | 9223372036854775807 |
| ULLONG_MAX | Maximum value for a variable of type unsigned long long | 18446744073709551615 (0xffffffffffffffff) |
If a value exceeds the largest integer representation, the Microsoft compiler generates an error.
