title: Trying to compare strings in 2d array
body: <p>So I have created a file that has a bunch of words in it, and my program is supposed to open the file, put all of the words in an array, and then compare the strings to see if any are exact matches. It opens the file and populates the array, but the problem comes when I am trying to compare the strings.. Can anyone tell me how to go about fixing why this isn't comparing properly?</p>
  
  <p>My words file:  </p>
