<p>Why does the linked code print:</p>
<pre><code>27 >= 20
9 20
</code></pre>
<p>in the order that it does? Why does it not print: </p>
<pre><code>9
27>=20
20
</code></pre>
<p>Thanks.</p>

<hr/>**评论：**<br/><br/>TheMerovius: <pre><p>Because first, the arguments to <code>fmt.Println</code> are evaluated and <em>then</em> it is called. In this case, first <code>pow(3,2,10)</code> gets evaluated, then <code>pow(3,3,20)</code>, which executes the <code>fmt.Printf</code> from <code>pow</code> and then <code>fmt.Println</code> get called with the results of both <code>pow</code>-calls (which prints the 9 and 20).</p></pre>jtambor: <pre><p>It seems so obvious now that you've explained it... Thanks a lot.</p></pre>
