Hi All,

I'm trying to reverse the order of bits in C (homework question, subject: bitwise operators). I found this solution, but I'm a little confused by the hex values (?) used -- 0x01 and 0x80.

  unsigned char reverse(unsigned char c) {
     int shift;
     unsigned char result = 0;

     for (shift = 0; shift < CHAR_BITS; shift++) {
        if (c & (0x01 << shift))
        result |= (0x80 >> shift);
     }
     return result;
  }

The book I'm working out of hasn't discussed these kinds of values, so I'm not really sure what to make of them. Can somebody shed some light on this solution? Thank you!
