#include <iostream> int main() { unsigned char n = 0; unsigned char Data = 0xff; unsigned char temp = 0; temp = Data; for (n = 0; n < 8; n++) { if (temp & 0x80 == 0x80) { std::cout << "1 "; } else { std::cout << "0 "; } temp = Data << n; } }

代码改成这样试试：

      for (n = 0; n < 8; n++)
      {
            if ((temp & 0x80) == 0x80)
               {
                     std::cout << "1 ";
               }
               else
               {
                     std::cout << "0 ";
               }
               temp <<= 1;
      }
