WebFeb 4, 2016 · Thus, it must result in a value of 0 to 32 (0 is when all is 0, 32 is when all is 8), which is the number of bit 1 in the variable x. And thus the function is named bitCount. That is how the function works. Final note: knowing this, you could even change m1 with 0x0F (instead of 0xFF) and the result would still be the same.
