body: <p>Can I add member variables to a structure, after i have declared it?
  For example:    </p>
  
  <pre><code>struct address 
      { 
         char name[50]; 
         char street[100]; 
      };
  </code></pre>
  
  <p>Can i dynamically (through code), add another member variable to the structure? Using something like <em>address.addMember(pinCode);</em> if something like this exists!</p>
  
  <pre><code>struct address 
      { 
         char name[50]; 
         char street[100]; 
         int  pinCode;
      };
  </code></pre>
