<b>Alignment of Braces</b>.
Note that since braces must be on a separate line (see above), this indentation by two spaces has an interesting property:
All C statements (and case selectors) like on lines that are odd multiples of 2 spaces: 2, 6, 10, ... (2*n + 1).
A braces lie on a separate line indented by an even multple of 2 spaces: 4, 8, 12, ... 2*n.
</p>
<ul>
<li><p>
All C statements (and case selectors) lie on lines that are multiples of 4 spaces (beginning with an indentation of two): 2, 6, 10, ... (4*n + 2) (for indentation level n = 0, 1, ...)
</p></li>
<li><p>
braces lie on a separate line also indented by multiple of 4 spaces: 4, 8, 12, ... 4*n (for indentation level n = 1, 2, ...)
</p></li>
</ul>
<p>
Thus, all code at the indentation level should align on the same column.
Similarly, opening and closing braces at the same indentation level should also align on the same (but different) column.
