"WebJun 21, 2024 · We can generate all possible subset using binary counter. For example: Consider a set 'A' having elements {a, b, c}. So we will generate binary number upto 2^n - 1 (as we will include 0 also). Here n is 3 so we will generate binary number upto 2^3 - 1 (i.e 8-1 = 7) Then we will check which bit in binary counter is set or unset. " - Bit manipulation in c programs

WebJun 25, 2009 · Actually, I've gone one step further here, and implemented a class called Flags that provides member functions for manipulation of bit flags. My base class uses atomic operations (handy when setting and testing in different threads), and I've even derived from it in a few cases to store flag state in the Windows registry automatically … WebC has direct support for bitwise operations that can be used for bit manipulation. In the following examples, n is the index of the bit to be manipulated within the variable bit_fld, which is an unsigned char being used as a bit field. Bit indexing begins at 0, not 1. Bit 0 is the least significant bit. Set a bit bit_fld = (1 << n) Clear a bit
