WebAug 29, 2024 · Below is an example of extracting a subset of the bits in the value: Mask: 00001111b Value: 01010101b Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits. Thus we have extracted the lower 4 bits. The result is: Mask: 00001111b Value: 01010101b Result: 00000101b WebApr 6, 2024 · To create a vector in C++, you need to include the header file and declare a vector object.
