title: How to convert a hexadecimal number into Ascii in C
body: <p>I plan to make a program like this:</p>
  
  <pre><code>loop
  
   read first character
   read second character
  
   make a two-digit hexadecimal number from the two characters
   convert the hexadecimal number into decimal
   display the ascii character corresponding to that number.
  
  end loop
  </code></pre>
  
  <p>The problem I'm having is turning the two characters into a hexadecimal number and then turning that into a decimal number. Once I have a decimal number I can display the ascii character. </p>
