Note: I'm a beginner.

I have a file with questions (lines ending with a "?") followed immediately with answers, then a new line break:

$ cat quiz.txt
Name 2 shapes?
square
circle

Which continent is north of South America?
North America

Who was the 1st person on the moon?
Neil Armstrong

I'm trying to create a perl script that prompts me with the question, followed by my <STDIN> and then displays the answer/s. Just as simple as that. No evaluation of whether the answer is correct and no score measurements etc..

I've done a perl one-liner that can prompt me the questions successfully:

$ perl -le '@array_q = `cat quiz.txt | grep ?`; foreach(@array_q){ print ; chomp($enter=<STDIN>) ; print "\n";}'

I then did another one-liner that can probe me for the answer:

$ perl -le '@array_ans = `cat quiz.txt | grep -v ?`; foreach(@array_ans){ print ; chomp($enter=<STDIN>) ; print "\n";}'

Since I had the 2 components of my quiz engine, I thought it would be simple combining the 2 one-liners using a nested foreach loop, but I'm running into all sorts of problems:

perl -le '@array_ans = `cat quiz.txt | grep -v ?`; foreach(@array_ans){ @array_q = `cat quiz.txt | grep ?`; foreach(@array_q){ print ; chomp($enter=<STDIN>) ; print "\n";} print;}'

The output is all over the place and not what I expected.

Now I'm not necessarily interested in the answer, but more if I'm thinking about this problem in the correct way. After chewing on this issue for a week, I'm thinking along the lines of hashes being more appropriate since a quiz question can be associated with an answer. Any advice please?

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
