title: Vector pointer and push_back()
body: <p>If I have</p>
  
  <pre><code>void f(vector&lt;object&gt; *vo) {
  
  }
  </code></pre>
  
  <p>And I pass the address of a vector to f</p>
  
  <pre><code>vector&lt;object&gt; vo;
  f(&amp;vo);
  </code></pre>
  
  <p>How would I use <code>push_back()</code> to add to the vector?</p>
