Convert Hex to Byte in C++
<p>How do you convert a hex string to short in c++?</p>

<p>Let's say you have </p>

<pre><code>string hexByte = "7F";
</code></pre>

<p>How do you convert that to a byte? Which I assume it's a <strong>char</strong> or <strong>int8_t</strong> in c++</p>

<p>I tried:</p>

<pre><code>wstring hexString = "7F";
unsigned char byte;
stringstream convert(hexString);
convert &gt;&gt; byte;
</code></pre>
