How do I perform const_cast in this case correctly?
<p>I have a function </p>

<pre><code>static bool Validate(const char&amp; letter, string&amp; aWord)
</code></pre>

<p>I need to invoke it</p>

<pre><code>Validate(letter, aWord); // where aWord is const
</code></pre>

<p>What is the correct way to const_cast in this case?</p>
