WebFeb 23, 2014 · Well, if you want to get rid of the other 3 bytes then you can do: thing = thing & 0x000000FF; where thing is an unsigned int. A 32-bit unsigned integer (i.e. unsigned int thing) allows you to have 32 bit flags. So, it is really straightforward to deal with bit flags. First you setup your defines for the 8 bit flags (i.e. lower 8 bits): WebC++ Utilities library std::bitset Constructs a new bitset from one of several optional data sources: 1) Default constructor.

WebFeb 22, 2024 · Defining bit masks in C++14 The simplest set of bit masks is to define one bit mask for each bit position. We use 0s to mask out the bits we don’t care about, and 1s to denote the bits we want modified. Although bit masks can be literals, they’re often defined as symbolic constants so they can be given a meaningful name and easily reused.
