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. WebAvenue Pixel Sdn.
