So I decided that the thing to do after spending all day and failing at that, is to split the 8-bit number into 4 2-bit numbers. So, if I ended up with, say, 95, it would print

%01, %01, %11 and %11 on the screen (or 1, 1, 3, 3). But I'm having trouble with even this. I figured all that was was a matter of shifting numbers left and right, but I shifted them left and right in various ways in an attempt to make it work, but to no avail. I wish I was smart like you guys.
