Webb14 dec. 2010 · In general: value = (value & ~mask) (newvalue & mask); mask is a value with all bits to be changed (and only them) set to 1 - it would be 0xf in your case. … WebbThe idea is to use bitwise << and & operators. Using the expression 1 << (k - 1), we get a number with all bits 0, except the k'th bit. If we do bitwise AND of this expression with n, i.e., n & (1 << (k - 1)), any non-zero value indicates that its k'th bit is set. For example, consider n = 20 and k = 3. 00010100 & (n = 20) 00000100 (1 << (3-1))
