<p>what is result of operator ',' by standard? Last argument? 
in code like this, for example:</p>

<pre><code>int a = 0;
int b = 1;

while(a,b);
</code></pre>

<p>or using it like this is not allowed? MSVS thiks that result is b, is it true?</p>

<p>sorry for duplicating, did not know how this operator called in english )</p>
