WebThis is known as the 'Hamming Weight', 'popcount' or 'sideways addition'. Some CPUs have a single built-in instruction to do it and others have parallel instructions which act on bit vectors. Instructions like x86's popcnt (on CPUs where it's supported) will almost certainly be fastest for a single integer. Some other architectures may have a slow instruction … WebJan 9, 2010 · Note that int and long are the same size and if you want a 64 bit integer then you need to use long long (or unsigned long long). 6 comments.
