set -clear bit

void UnsetBit(WORD &data, int bit){int i = 1;// shift bits by i valuei = i << bit;// inverse bitsi = ~i;// set bit to 0data &=i;}

void ClearBit(WORD &data, int bit){assert( (bit >= 0) && (bit < sizeof(WORD)*8 );WORD bitmask = ~(1 << bit);// set bit to 0data &=bitmask;}

Original post by Moomin void UnsetBit(WORD &data, int bit){int i = 1;// shift bits by i valuei = i << bit;// inverse bitsi = ~bit;// set bit to 0data &=i;} Edit : i ~= bit; to i = ~bit;

// inverse bitsi = ~i;

// inverse bitsi = ~bit;
