title: C++ map of pointers to maps
body: <p>Related to a different question I have posted for which I am trying to find a solution some how - <a href="https://stackoverflow.com/questions/16577724/c-dynamic-way-to-determine-the-container-to-use">C++ dynamic way to determine the container to use</a></p>
  
  <p>Noticed similar links:</p>

  <p>Edited - From int to float.. </p>
  
  <p>Edit 2 - the following seems to have some solution for this at this link - but need to somehow translate for this problem at hand.. </p>
  
  <p><a href="https://stackoverflow.com/questions/12157303/how-to-create-instance-of-a-class-when-the-class-name-is-stored-in-another-varia?rq=1">How to create instance of a class when the class name is stored in another variable</a></p>
  
  <p>I have the following structure:</p>
  
  <pre><code>Class Items
  {
    float itemType;
    float itemPrice;
    Items(){};
    ~Items(){};
  };
  
  typedef std::unique_ptr&lt;Items&gt; pptr;
  typedef std::pair&lt;float, pptr&gt; itemsRec;
  std::multimap&lt;float, pptr&gt; mapItems;
  </code></pre>
  
  <p>Need help with creating a new map of mapItems... can any one help with the syntax to create this new map of mapItems? Let's assume "A" gets derived by other means.</p>
  
  <p>Thanks</p>
  
  <pre><code>std::map&lt;string, pointer to mapItems&gt; myMap;  // What's the syntax for this?
  
  myMap["A"]={create a new map - mapItems_A and assign pointer here};
  </code></pre>
  
  <p>Thanks.</p>
  
  <p>Edit 3 - Still exploring options - Looks like the following link has some interesting stuff that might be helpful in my case to define the container dynamically.. Exploring further. </p>
