title: How can I combine multiple char's to make a string?
body: <p>I am doing string parsing and essentially what I would like to do is something like this:</p>
  
  <pre><code>string signature = char[index+1] + '/' + char[index+2];
  </code></pre>
  
  <p>BUT you can't do string concatenation on char's so that brings me to this question, how can I simulate concatenation on char's?</p>
  
  <p>I know that the string library in C++ has append but I don't think that works for my case.  Any ideas?</p>
