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.

WebJan 26, 2014 · Some advice - when bit-fiddling, it's a good idea to use unsigned integer types. C doesn't guarantee that signed integers will use any particular representation - without a clear definition of how numbers translate to/from bits, bit-fiddling is very bug-prone. In practice the representation will be twos complement for any not-completely-strange ... WebFeb 19, 2005 · Hey, I'm doing a homework problems and am very stuck.
