}</pre>
</div> <p>this is completely equivalent to: </p> <div class="example smallexample"> <pre class="example-preformatted" data-language="cpp">id array = …;

{
  id object;
  for (object in array)
  {
    /* Do something with 'object'  */
  }
}</pre>
</div> <p>but can save some typing. </p> <p>Note that the option <samp class="option">-std=c99</samp> is not required to allow this syntax in Objective-C. </p> </div><div class="_attribution">
