Without using vectors, I need to fix this program to test users on the Spanish vocab word for an English word. The voacb$1.$txt has both pairs of words with a space seperating them. This program does not actually quize the user or caculate overall totals for the total number of quizzes taken, quizzes pased, quizzes failed, or total words reviewed throughout all quizzes.
