I am trying to add the question taken from the .txt file to the array of questions I have setup in the Holder class but I am getting an uninitalized error on
return WC
Which I can understand because I am never setting WC to anything but I can't think of another solution that doesn't involve adding in another class which I can't due do to project limitations. Any suggestions would be greatly appreciated.
