title: Object variables in C++ hold values, not object references
body: <p>At: <a href="http://www.horstmann.com/ccj2/ccjapp3.html" rel="noreferrer">http://www.horstmann.com/ccj2/ccjapp3.html</a>, under <strong>A3.4. Objects</strong>, mentioned the following:</p>
  
  <blockquote>
    <p>In C++, object variables hold values, not object references</p>
  </blockquote>
  
  <p>Can you clarify this point? And, is it only the <code>pointer</code> in C++ that holds object references?</p>
  
  <p>Can we say here that the <code>object reference</code> is the <code>object address</code>?</p>
  
  <p>Thanks.</p>
