title: How are iterators and pointers related?
body: <p>Code with iterators looks pretty much like code with pointers. Iterators are of some obscure type (like <code>std::vector&lt;int&gt;::iterator</code> for example).</p>
  
  <p>What I don't get is how iterators and pointer are related to each other - is an iterator a wrapper around a pointer with overloaded operations to advance to adjacent elements or is it something else?</p>
