C++ convert uint16_t to int
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 ...
