<p>The <a href="qscopedarraypointer.html">QScopedArrayPointer</a> class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction.</p>
<p>A <a href="qscopedarraypointer.html">QScopedArrayPointer</a> is a <a href="qscopedpointer.html">QScopedPointer</a> that defaults to deleting the object it is pointing to with the delete[] operator. It also features operator[] for convenience, so we can write:</p>
<pre class="cpp">
<span class="type">void</span> foo()
{
<span class="type"><a href="qscopedarraypointer.html#QScopedArrayPointer">QScopedArrayPointer</a></span><span class="operator"><</span><span class="type">int</span><span class="operator">></span> i(<span class="keyword">new</span> <span class="type">int</span><span class="operator">[</span><span class="number">10</span><span class="operator">]</span>);
i<span class="operator">[</span><span class="number">2</span><span class="operator">]</span> <span class="operator">=</span> <span class="number">42</span>;
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
<span class="keyword">return</span>; <span class="comment">// our integer array is now deleted using delete[]</span>
