Question

I have a byte A and byte B. I am looking for byte C which is every other bit from A and every other bit from B. So if A = 10011010 and B = 01110010 then C would be 10110101 where 1011 is every other bit from A and 0101 is every other bit from B. Can anyone help me with this?

Answer 1

Try this:

byte C = (byte)(
    (A & 0x80) |
    ((A & 0x20) << 1) |
    ((A & 0x08) << 2) |
    ((A & 0x02) << 3) |
    ((B & 0x80) >> 4) |
    ((B & 0x20) >> 3) |
    ((B & 0x08) >> 2) |
    ((B & 0x02) >> 1));
