title: How to create Array of Dynamic Arrays in C++
body: <p>I am trying to learn C++ and trying to write a code for a simple hash table like following structure:</p>
  
  <pre><code>array[0][0] array[0][1] array[0][2]
  key 1        value 1      value 2
  
  array[1][0] array[1][1] 
  key 2        value 3     
  
  array[2][0] array[2][1] array[2][2]
  key 3        value 4      value 5
  </code></pre>
  
  <p>means Array of Dynamic Arrays. Now, I can't understand how to define the array like that ?</p>
  
  <p>Any help on this will be grateful.</p>
