I hope you understand difference between this:
  
else
      cout &lt;&lt; "There are two adjacent elements where "
           &lt;&lt; "the second is twice the first."
           &lt;&lt; "\n They have values of " &lt;&lt; *(result2++);
      cout &lt;&lt; " &amp; " &lt;&lt; *result2 &lt;&lt; "." &lt;&lt; endl;

... and this:
else
   {
      cout &lt;&lt; "There are two adjacent elements where "
           &lt;&lt; "the second is twice the first."
           &lt;&lt; "\n They have values of " &lt;&lt; *(result2++);
      cout &lt;&lt; " &amp; " &lt;&lt; *result2 &lt;&lt; "." &lt;&lt; endl;
   }
