逆置整型数的二进制码

/* reverseBits.c ----把value的二进制位模式从左到右逆置,返回值是逆置后的数** dhfalive 2010.8 [e-mail]*/unsigned reverseBits(unsigned value){unsigned result = 0;int bitsCnt = sizeof(unsigned) * 8;//unsigned int 在内存中的位数int i;for (i = 1; i < bitsCnt; i++){result += (value & 1);value >>= 1;result <<= 1;}return result;}
