title: Difference between %255[^\0]s and %255c
body: <p>In C, when using sscanf, for the format parameter, is there a difference between using:</p>
  
  <pre><code>%255[^\0]s
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>%255c
  </code></pre>
  
  <p>Is one faster? Will one of the above ever give a different outcome?</p>
