title: What is the difference between {0} and +?
body: <p>Is there any difference between the use of <code>{0}</code> and <code>+</code> as they both are doing the same work of printing the <em>length</em> on the screen:</p>
  
  <pre><code>Console.WriteLine("Length={0}", length);
  Console.WriteLine("Length="   + length);
  </code></pre>
