title: Format string placeholders
body: <p>Do format string placeholders have a more technical name?</p>
  
  <p>For example,</p>
  
  <pre><code>int currentYear = DateTime.Now.Year;
  Console.WriteLine("The current year is {0}.", currentYear);
  </code></pre>
  
  <p>If you were reading this code out loud, or to yourself, how do you read the placeholder? Is there a correct term for representing them?</p>
