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 ... Web3. Use the btest test harness to check your functions for correctness. 4.
