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="smallexample"> foo (float f, float g)
|
|
{
|
|
float beat_freqs[2] = { f-g, f+g };
|
|
/* <span class="roman">...</span> */
|
|
}
|
|
</pre>
|
|
</body></html>
