To display bit number i of the variable n, we shift n i bits to the right, so
that the bit we want to display is all the way to the right.  Then we say & 0x1
to zero out all the other bits, so that the only surviving bit is the bit we
want to display (the bit that was originally in bit number i).

The parentheses around (n >> i) are not necessary.  Even without the
parentheses, the >> would execute before the & because the >> has higher
precedence.
