A program with #include<iostream.h>, allows the use of string functions like strlen(). Why?
<pre><code>#include&lt;iostream.h&gt;
int main()
{
   char name[] = "Mary Mon";
   cout&lt;&lt;strlen(name);
   return 0;
}
</code></pre>

<p>This program compiles normally without <code>#include&lt;string.h&gt;</code>. Why?</p>
