title: C++ Iterate from the second element of a map
body: <p>I have a <code>std::multimap</code> on which I am iterating using a forward iterator.</p>
  
  <pre><code>std::multimap&lt;int,char&gt;::iterator it;
  for(it=map.begin();it!=map.end();++it) {
      // do something
  }
  </code></pre>
  
  <p>Now I need to treat the first element differently and start iterating from the second element of the map. How do I do that?</p>
