what is the difference between &c and *c declaration?
<p>I don't understand:
What is the difference between:</p>

<pre><code>string Str ("Str");
char &amp;C = Str [0];
</code></pre>

<p>and this:</p>

<pre><code>string Str ("Str");
char *C = Str;
</code></pre>

<p>I don't understand this declaration actually:</p>

<pre><code>char &amp;C = Str [0];
</code></pre>

<p>?</p>
