title: Extract Number from Char* Array (C-String)
body: <p>I have a string that occurs in this format:</p>
  
  <p><code>.word 40</code> </p>
  
  <p>I would like to extract the integer part. The integer part is always different but the string always starts with <code>.word</code>. I have a tokenizer function which works on everything except for this. When I put <code>.word</code> (.word with a space) as a delimiter it returns null.</p>
  
  <p>How can I extract the number?</p>
  
  <p>Thanks</p>
