title: How do I use strtok with every single nonalpha character as a delimeter? (C)
body: <p>So I have a string:</p>
  
  <pre><code>**BOB**123(*&amp;**blah**02938*(*&amp;91820**FOO**
  </code></pre>
  
  <p>I want to be able to use <code>strtok</code> to deliminate each word. The delimiter is every single character that is not a letter. </p>
  
  <p>I was suggested to us <code>isalpha</code>, but not sure how I would go about this. Is there a way to do this without naming every single non-alpha character? </p>
  
  <p>Unfortunately NOT allowed to use regex libraries.</p>
