title: Assigning empty value to char
body: <pre><code>char myChar; 
  </code></pre>
  
  <p>To be clear the above is what I mean by an "empty" value. </p>
  
  <pre><code>while(conditions)
  {
  userInput
  if(userInput) 
    {do stuff}
  
  assign userInput empty value  *where I need help
  }
  </code></pre>
  
  <p>How do I reset my char value to nothing to prevent the if statement from running after looping with previous userInput? I read that you can't assign a pointer value (null) to char, what would I then do?</p>
