title: Placing units after an input
body: <p>I'm making finishing touches on one of my programming homework problems, and I'd like to make my program list the kind of units directly after the input in the terminal input, <em>before</em> the user actually enters the input itself.</p>
  
  <p>Essentially, I'd like to make the system output the following line in the terminal window, with [] being a blinking cursor for the user's next input:</p>
  
  <blockquote>
    <p>Input a number in inches: [] inches</p>
  </blockquote>
  
  <p>Any ideas?</p>
