Need some help with struct variable assignment in functions

<p>I&#39;m still learning the syntax candy and I need a class-like object, so I&#39;ve turned to structs. I&#39;m not sure why the code in my example below isn&#39;t assigning a value I&#39;m attempting. Can anyone give me some insight about how to proceed with this? </p> <p><a href="https://play.golang.org/p/E74NBnDWuU" rel="nofollow">https://play.golang.org/p/E74NBnDWuU</a></p> <hr/>**评论：**<br/><br/>fr4nk3n: <pre><p>You have to use a pointer to the struct. <a href="https://play.golang.org/p/oTUkjV1UTP" rel="nofollow">https://play.golang.org/p/oTUkjV1UTP</a></p></pre>Marvelt: <pre><p>You need to pass the receiver as a pointer in order to update it.</p> <p><a href="https://play.golang.org/p/etJKmvp5H8" rel="nofollow">https://play.golang.org/p/etJKmvp5H8</a></p></pre>igknighted: <pre><p>Thanks.
