{There are many different ways to do multiple choice tests.
The correct answers should not all be the same char. One
way is to let the computer do most of the work by putting all
the questions and answers in a text file in a fixed format with
some way of identifying the correct answer. Now you can use a
single procedure to display questions and answers for any exam
you want to make with different numbers of choices.}
