C Sized Integer Types

Microsoft Specific

Microsoft C features support for sized integer types. You can declare 8-, 16-, 32-, or 64-bit integer variables by using the __intn type specifier, where n is the size, in bits, of the integer variable. The value of n can be 8, 16, 32, or 64. The following example declares one variable of each of the four types of sized integers:

__int8 nSmall;      // Declares 8-bit integer
__int16 nMedium;    // Declares 16-bit integer
__int32 nLarge;     // Declares 32-bit integer
__int64 nHuge;      // Declares 64-bit integer

The first three types of sized integers are synonyms for the ANSI types that have the same size, and are useful for writing portable code that behaves identically across multiple platforms. Note that the __int8 data type is synonymous with type char, __int16 is synonymous with type short, and __int32 is synonymous with type int. The __int64 type has no equivalent ANSI counterpart.
