title: C# - Bubble-sorting an array of chars alphabetically
body: <p>I was given this by my teacher:</p>
  
  <pre><code>int[] letters = { 'c', 's', 'a', 'k', 'x', 'l', 'j' };
  </code></pre>
  
  <p>and told that I should convert the chars to int and then bubble-sort them alphabetically and back to char and save and print the array alphabetically.</p>
  
  <p>I've only every come across bubble sorting when it deals with numbers but not when using chars. Any assistance or enlightenment is greatly appreciated. </p>
