WebJul 14, 2014 · C num = ( 1 << n); to set the bit n of num (for instance num = (1 << 0); sets the bit 0 ). To set (clear) multiple bits you have just to OR ( AND) the num with the appropriate constant. For instance C num = 0xFF; sets the bits 0..7 of num while C num &= ~0xFF; clears the same bits.
