WebOct 20, 2012 · The above won't count the number of bits in a character, it will count the number of set bits (1 bits). For example, the following call will return 4: char c = 'U'; countbits (c); The code: ch = ch & (ch - 1) Is a trick to strip off the right most (least significant) bit that's set to 1. So, it glosses over any bits set to 0 and doesn't count them. WebNov 21, 2024 · 10. Method 3: Using bit mask. To set a bit, we can take OR of 1 and that bit (as 1 1 = 1, and 1 0 = 1). Therefore, to set all odd bits of an n-bit number, we need to use a bit mask which is an n-bit binary number with all odd bits set. This mask can be generated in 1 step using the formula of sum of a geometric progression, as an n bit ...
