title: In C, what happens when the condition for a for loop aren't met at the beginning?
body: <p>For example, what happens if I say:</p>
  
  <pre><code>for(i = 2; i &lt; 2; i++)
  </code></pre>
  
  <p>Obviously, this is a useless for loop, but maybe i = a, and a is set by something else. So what happens in this case?</p>
