title: Map inside a Map
body: <p>The key string of _map represents the name of a film. 
  The key int of the second map represent the year. And the string of the inside map representes all the translations of the film. I want to store more thant a translation per year and per film</p>
  
  <pre><code>map&lt;string,map&lt;int, string&gt; &gt; _map;
  map&lt;int, string&gt;  _insideMap;
  int year;
  cin &gt;&gt; year;
  _insideMap[int]="Los Vengadores";
  _map["The Avengers"]=_mapaDins;
  </code></pre>
  
  <p>So after that I have to add another translation of the film The Avengers, in russian for example. 
  So I do the same again  and the value Los Vengadores is replaced for "russian name" Also I have tried this but it doesn't work:</p>
  
  <pre><code>it2=_map.find("The Avengers");
  it2.second.insert(2013,"russian translaiton");//erorr
  </code></pre>
  
  <p>How i have to do it the insert?</p>
  
  <p>The Avengers -></p>
  
  <p>2010 Los Vengadorse</p>
  
  <p>2013 "russian name"</p>
  
  <p>next film -></p>
  
  <p>Thank oyu</p>
