title: Iterating through a 2d Vector row
body: <p>I am working on a homework assignment for my C++ class.  </p>
  
  <p>I am trying to iterate through a 2d multidimensional vector. I have all the data in the 2d vector which is size <strong>7x7</strong> i.e. <code>0-6 by 0-6</code>,.  </p>
  
  <p>Problem is I need to output the contents of the 2d vector in the order of <code>alphaV[0][0], alphaV[1][0], alphaV[2][0],</code> etc.  </p>
  
  <p>When I try to use a nested <code>For</code> loop to process this vector I run into problems whereby the rows of the vector will not iterate, that is to say they remain at index 0.   </p>
  
  <p>So it keeps repeating a<code>lphaV[0][0], alphaV[0][0], alphaV[0][0],</code> etc.</p>
  
  <p>How do I go about iterating the columns in that pattern <code>[0][0], [1][0], [2][0]</code> ...?</p>
