<p>Asked the question already but haven't gotten satisfiable answers; 
So can someone clear the following code on the level beginner could understand [I'm a beginner], it's from the book C++ From The Ground Up 3rd edition by Herbert Schildt</p>

<pre><code> int i, j;

 for(i=2; i&lt;16; i++) {
  for(j=2; j&lt;=(i/j); j++) //In this line I'm confused with the condition logic 
   if(!(i%j)) break ; 
  if(j&gt;(i/j)) cout&lt;&lt;i&lt;&lt;" / "&lt;&lt;j&lt;&lt;endl; //This line confuses me most
  }
</code></pre>
