title: Read char array, one char at a time
body: <p>My program saves user input as a string (UI), then splits it into an array 
  <code>char[] charArray = UI.toCharArray();</code> After this the program needs to read the first letter in <code>charArray</code>, use it for different part of the program, and then proceed to the next letter in the array. The problem is reading the array one letter at a time.</p>
  
  <p>How do you access each character in an array in order?</p>
