expression must have a constant value in c++
<p>So, I am creating an object that have an array as it's instance. The size of this array will determined by the client program. Later in my program, I have to create a temp array that have the same capacity as the instance variable. So, I put:</p>

<pre><code>int temp[capacity];
</code></pre>

<p>However, when I try to compile it, it failed. It said that I have to have a fix value instead of putting capacity. Any idea how can I fix this problem? thx</p>
