Sep 26, 2017 · Why are "bit masks" called like this? I know that they are mainly used for bitwise operations and the usage of bit masks is more efficient than the usage of separate variables. …

Feb 27, 2025 · The algorithm being designed for 32-bits makes the most sense, and the interoperability with other languages other answers mention sort does as well to an extent. The only remaining …

What approach do you use when dealing with bit fields and why? Of course since all three approaches work, I'm looking for factual and technical reasons, generally accepted conventions, and not simply …

Jun 15, 2016 · Agreed, I used to support an application that used bit masks for user roles and privileges in its database. It was a nightmare. Using a 32 bit int, we ran out of bits, so somebody had the great …

Mar 29, 2016 · The actual question Why would one choose a bitwise mask as a representation of a selection of a (finite/bound) amount of items, instead of an array of the selected items? Given that …

I thought about using a map instead, with the mask value (1,2,4,8...256) as key field and the calculated data in the value field. But would prefer to keep the static array.

Jan 6, 2015 · This makes it trivial to perform case-insensitive searches via simple bit mask logic. Certainly it is much easier than with some Unicode-encoded characters that need to be decoded into …

If you are assuming you are implementing C, you can apply a mask to the variable. For example: a = 0xF2 // Binary: 11110010 b = 0xF6 // Binary: 11110110 mask = 0x04 // Binary: 00000100 c = a ^ …

For bit fields, the c and c++ language state that the compiler combines them into a larger unit (char, short, int, long or long long) and assigns them bit positions in an implementation defined way. So you …

Generally, is using bit-mask in SQL databases kind of anti-pattern? Backgrounds: The usage of these bit columns are left to be defined by the end user, along with a few of other int, float, double, varchar …
