title: What's the difference between --i and i--?
body: <p>In some code i've seen a for loop with a --i as third parameters </p>
  
  <pre><code>for(int i=array.length; i&lt;0; --i)
  </code></pre>
  
  <p>Maybe someone can explain me the difference with i-- ? </p>
  
  <p>i guess it's something like the moment when i is decremented ? </p>
