title: Can a 'for' loop inside of a 'for' loop use the same counter variable name?
body: <p>Can I use the same counter variable for a <code>for</code> loop inside of a <code>for</code> loop?</p>
  
  <p>Or will the variables affect each other? Should the following code use a different variable for the second loop, such as <code>j</code>, or is <code>i</code> fine?</p>
  
  <pre><code>for(int i = 0; i &lt; 10; i++)
  {
    for(int i = 0; i &lt; 10; i++)
    {
    }
  }
  </code></pre>
