我试图找出如何仅使用以下按位操作来添加位（最多2个字节）：〜＆amp; ^ | ＆LT;＆LT; ＆GT;取代。我一直试着没有运气。我想知道是否有人知道如何。
int logicalByteAdd(int x, int y) {
return ;
}
答案 0 :(得分：2)
unsigned short add(unsigned short a, unsigned short b)
{
unsigned short carry = a & b;
unsigned short result = a ^ b;
while(carry != 0)
{
unsigned short shiftedcarry = carry << 1;
carry = result & shiftedcarry;
result ^= shiftedcarry;
}
return result;
}
