I agree. That would be more efficient, specially with a lot of question-answer
sets, and cleaner code.
have all questions saved after each other, with the answers right after each q.
Then have a little table where you store the addresses of all the questions.
if you want question 5, pick out the fifth entry in the table, read the q until
you hit 0, then read in the answers. If you want different amount of answers to
each question, put in a little byte here telling how many answers to read.
If you build it up like this, it is very easy to add new questions, just put
them in, expand the table by one entry and increase the range of the
randomfunction.
