2023年8月28日 · @Ezh And yet many languages that support a 'byte' data type also support performing arithmetic on that type (e.g. Java, C#, Kotlin, Go). The strict, pedantic definition of a byte may well say nothing about performing arithmetic, but the strict definition is not necessarily the same as people's expectations. (Or to put it another way, there's ...

2015年6月28日 · A byte is 8 bits, and an array of byte, is an array of bytes... It really is that simple. The thing to keep in mind is that char and byte are different. In old C style, a char and byte were basically the same thing. In .NET, characters are Unicode and can be anywhere from 8-32 bits per character. This is where encoding comes into play.

The definition is (meanwhile?) located in minwindef.h, which is included by windef.h. And windef.h is included by Windows.h. ... Unfortunately they don't use a define like _BYTE_DEFINED in wtypes.h for Win16 types or BASETYPES in minwindef.h for ULONG, USHORT and UCHAR. –

2008年9月17日 · In this case, some characters take more than 1 byte to store in the database. If you define the field as VARCHAR2(11 BYTE), Oracle can use up to 11 bytes for storage, but you may not actually be able to store 11 characters in the field, because some of them take more than one byte to store, e.g. non-English characters.

2019年9月23日 · std::byte has cause quite a bit of havoc, collides pretty heavily with RPC sensibilities from the 1980s. Add _HAS_STD_BYTE=0 to the preprocessor definitions. Or just put the code in its own .cpp file so you don't have to #include any windows headers.

2022年5月12日 · If you want to set/clear single bits, you first need to fetch the corresponding byte from memory, mess with the bits and then write the byte back to memory. By contrast, one definition for word is the biggest chunk of bits with which a processor can do processing (like addition and subtraction) at a time – typically the width of an integer ...

Since the C++ spec says that a char* must point to individual bytes, and the PDP-6/10 does not allow addressing individual bytes in a word, you have a problem with char* (which is a byte pointer) on the PDP-6/10. So one work around is: define a byte as 9 bits, then you essentially have 4 bytes in a word (4 * 9 = 36 bits = 1 word).

2017年12月7日 · I am trying to understand, what would be the best way to define BYTE, WORD and DWORD macros, which are mentioned in answers of this question.

2012年9月7日 · The weird situation I'm having trouble understanding is, how can I get a byte[] for the class definition of something like [LNonIntrinsicType - in other words, if my application requests the class definition for an instance of NonIntrinsicType[], I don't have a *.class file that corresponds to this class type.

2011年11月28日 · byte. addressable unit of data storage large enough to hold any member of the basic character set of the execution environment. and §5.2.4.2.1: CHAR_BIT — number of bits for smallest object that is not a bit-field (byte) Thus, a "byte" contains CHAR_BIT bits.
