  15 <H2>section 3.2: If-Else</H2>
  16
  17 <p>The syntax description here may seem to suggest
  18 that <I>statement</I><tt>&lt;sub&gt;</tt>1<tt>&lt;/sub&gt;</tt> and <I>statement</I><tt>&lt;sub&gt;</tt>2<tt>&lt;/sub&gt;</tt>
  19 must be single, simple statements,
  20 but,
  21 as mentioned
  22 in section 3.1,
  23 a block of statements enclosed in braces <TT>{}</TT>
  24 is equivalent to a single statement.
  25 </p><p>page 56
  26 </p><p>``Coding shortcuts''
  27 like
  28 <pre>   if(expression)
  29 </pre>can indeed be cryptic,
  30 but they're also quite common,
  31 so you'll need to be able to recognize them
  32 even if you don't choose to write them in your own code.
  33 Whenever you see code like
  34 <pre>   if (x)
  35 </pre>or
  36 <pre>   if (f())
  37 </pre>where <TT>x</TT> or <TT>f()</TT>
  38 do not have obvious ``Boolean'' names,
  39 just mentally add in
  40 <TT>!= 0</TT>.
  41 </p><p>Don't worry too much if the multiple <TT>if</TT>/<TT>else</TT> ambiguity
  42 described on page 56
  43 doesn't make perfect sense;
  44 just note the deep sentence:
  45 <blockquote>...it's a good idea to use braces when there are nested <TT>if</TT>s.
  46 </blockquote></p><hr>
