<h3 class="section">Non-Constant Initializers</h3>



   <p>As in standard C++ and ISO C99, the elements of an aggregate initializer for an

automatic variable are not required to be constant expressions in GNU C. 

Here is an example of an initializer with run-time varying elements:



<pre class="example">     foo (float f, float g)

     {

       float beat_freqs[2] = { f-g, f+g };

       /* <small class="dots">...</small> */

     }

     </pre>
