checking for 'null' slots in a object array
<p>Hi there
I have come form the java camp and am trying to do a c++ program </p>

<p>I have an array called Manifest that takes passenger objects</p>

<pre><code>for (int i = 0; i&lt; _totalSeats; i++) 
{
    if (Manifest[i] != instanceOf Passenger) {
        cout&lt;&lt;"empty"endl;
    }
    else {
        cout&lt;&lt; PassengerToString(i);
    }
}
</code></pre>

<p>obviously the 'instanceOf' is a problem in C++, 
I know is==null doesn't work as there is no such thing as null without being specificly inserted
but to build a blank passenger objects then insert them in each array slot sounds messy and costly.
Is there a more elegent way?</p>

<p>thanks</p>
