P.S. the calculator is supposed to convert the letter grade to the gpa score (A-->4.0) so if someone could explain how it would be done in an array instead that would help. I tried to do it, but I couldn't get that to work. This way is functional albeit long.
My main issue is the calculator's inability to calculate!
Thank you for any responses.
I cannot attach anything so I will include a pastebin link instead:
