title: Difference between postfix and prefix increment of stl iterators?
body: <p>Let us take: </p>
  
  <pre><code>x = list&lt;int&gt;::iterator
  y = list&lt;int&gt;::const_iterator
  z = vector&lt;int&gt;::iterator
  t = vector&lt;int&gt;::const_iterator
  </code></pre>
  
  <p>Is there any difference between:</p>
  
  <ol>
  <li><code>++x</code> and <code>x++</code>?</li>
  <li><code>++y</code> and <code>y++</code>?</li>
  <li><code>++z</code> and <code>z++</code>?</li>
  <li><code>++t</code> and <code>t++</code>?</li>
  </ol>
