Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <algorithm></span>
bool is_heap<span class="br0">(</span>iterator start<span class="sy0">,</span> iterator end<span class="br0">)</span><span class="sy0">;</span>
bool is_heap<span class="br0">(</span>iterator start<span class="sy0">,</span> iterator end<span class="sy0">,</span> StrictWeakOrdering cmp<span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The <span class="curid"><a href="../../stl/algorithm/is_heap.html" class="wikilink1" title="stl:algorithm:is_heap">is_heap</a></span>() function returns true if the given range [start,end) is a heap.
</p>
<p>
If the strict weak ordering comparison function object cmp is given, then it is
used instead of the < operator to compare elements.
</p>
<p>
is_heap() runs in <a href="../../complexity.html" class="wikilink1" title="complexity">linear time</a>.
