Yes, there is a better way: int CountOnesFromInteger (unsigned int value) { int count; for (count = 0; value != 0; count++, value &= value-1); return count; } The code relies on the fact that the expression x &= x-1; removes the rightmost bit from x that is set. We keep doing so until no more 1's are removed.

WebDec 31, 2024 · One way to go about this is to count the number of bits and check the least-significant bit to see if the value is odd or even if it's 1 or 0 respectively. Given a 32-bit integer, we can count the number of 1s in its binary representation, Hamming Weight, through some clever bit manipulation.There's a good answer on find the Hamming … WebOct 26, 2012 · I'm finishing up some CSE homework and I have a quick question about declaring integers of larger bit sizes.
