title: Iterating over unordered_map C++
body: <p>Is it true that keys inserted in a particular order in an unordered_map, will come in the <strong>same order</strong> while iterating over the map using iterator?</p>
  
  <p>Like for example: if we insert (4,3), (2, 5), (6, 7) in B.
  And iterate like:</p>
  
  <pre><code>for(auto it=B.begin();it!=B.end();it++) {
      cout&lt;&lt;(it-&gt;first); 
  }
  </code></pre>
  
  <p>will it give us 4, 2, 6 or keys may come in any order?</p>
