WebIn a bit mask, Bitwise AND can be used to make sure particular bits in the result value are set to 0. The trick is to put a 1 in the mask for any bit you do not want changed in the result, and a 0 in the mask for any bit that you want to make sure is a 0 in the result. WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined ... greenwood park church of christ youtube
