title: C++ any hex to char
body: <p>Is there a better way from hex to char?</p>
  
  <pre><code>char one = static_cast&lt;char&gt;(0x01);
  </code></pre>
  
  <p>(asking because of this --> <a href="https://stackoverflow.com/questions/6823216/c-using-pointers-nothing-is-passed">C++ using pointers, nothing is passed</a> )</p>
  
  <p>Also is there a fast way to make a char array out of hex values (eg. 0x12345678 to a char array)?</p>
