<DIV></DIV>&gt;I have been tasked with a problem in my newbie manual to use a "for loop" and to console out by 2's from 0 to 20 here's what I have done and I was wondering 1st why it doesn't work and 2nd how do I make it work. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;#include <IOSTREAM>
<DIV></DIV>&gt;int main() 
<DIV></DIV>&gt;{ 
<DIV></DIV>&gt; // --- iterate an integer by 2 
<DIV></DIV>&gt; for (int i = 0; i &lt;= 20; i+=2){ 
<DIV></DIV>&gt; std::cout &lt;&lt; i &lt;&lt; '\n'; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; // --- pause system 
<DIV></DIV>&gt; char end[5]; 
<DIV></DIV>&gt; std::cin &gt;&gt; end; 
<DIV></DIV>&gt; return 0; 
<DIV></DIV>&gt;} 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Thanks in advance 
<DIV></DIV>&gt;Danny
