<p>The example program below prints all multisets elements containing the values
<em>{0,1,2,3}</em> ordered by size.  Multiset elements of the same size are
ordered lexicographically.
</p>
<div class="example">
<pre class="verbatim">#include &lt;stdio.h&gt;
#include &lt;gsl/gsl_multiset.h&gt;

int
main (void)

  for (i = 0; i &lt;= 4; i++)
