I'm working on a programming project and one of things I need to do is write a function that returns a mask that marks the value of the least significant 1 bit. Any ideas on how I can determine the value using bitwise operators?
ex:
0000 0000 0000 0000 0000 0000 0110 0000 = 96
What can I do with the # 96 to turn it into:
0000 0000 0000 0000 0000 0000 0010 0000 = 32
I've been slamming my head against the wall for hours trying to figure this out any help would be greatly appreciated!
x &= -x; /* clears all but the lowest bit of x */
