    Syntax:

  #include &lt;cstdlib&gt;

</pre>

  <p>The function malloc() returns a pointer to a chunk of memory of
  size <em>size</em>, or <strong>NULL</strong> if there is an error.
  The memory pointed to will be on the heap, not the stack, so make
  sure to free it when you are done with it. An example:</p>
<pre class="prettyprint">
   typedef struct data_type {
     int age;
     char name[20];
   } data;

   data *bob;
   bob = (data*) malloc( sizeof(data) );
   if( bob != <strong>NULL</strong> ) {
     bob-&gt;age = 22;
     strcpy( bob-&gt;name, &quot;Robert&quot; );
     printf( &quot;%s is %d years old\n&quot;, bob-&gt;name, bob-&gt;age );
   }
   free( bob );
