title: Using ifstream::operator>> to load an array from a CSV file
body: <p>I know there are several C++ ways to load in values from a CSV, but I'm curious, how can I adapt this incorrect approach with the minimal changes necessary to make it work:</p>
  
  <pre><code>std::ifstream fileStream ("File.txt");    // File.txt reads "1,2,3"
  short numbers[3];
  
  for (short i = 0; i &lt; 3; ++i)
      fileStream &gt;&gt; numbers[i];
  </code></pre>
  
  <p>Is there any way that I can do this using ifstream::operator>>, while keeping as conceptually close as possible to this implementation? Fix this code! :-)</p>
  
  <p>Thanks! Believe it or not, this will be very helpful in a computational neutrino physics project I'm working on.</p>
