Help for my son
I am a programmer and i need help for my son in Perl. He has been asked to do this so I want to see how to go about it and use it as a tutorial. I have some knowledge in Perl.
This is the question: Write a Perl program (call it A.pl) that takes user entered lines from the keyboard and stores them in an array. When the user enters "quit", the program prints out all the lines sorted (ASCII order i.e. a line starting with an Ab
would print out before one starting with Ac
). Now modify the program (call it B.pl) so it tells you how many lines have been entered, and then prints out only lines 2, 3, and 4.

1. Forums are usually not for delivering programs to students having homework.
2. If you know Perl, you should be able to help your son, the task is really easy.
3. Sorry, I won't give any spoiler, even though it would take me 2 minutes. You should put you son to work.

I am only a beginner and I am not looking for the answer to spoonfeed him or make his work easy. If you can explain it to me I do the same for him. He has been working on it for a week now. I don't want him to get it easy that is why I joined the forum and not him. Please I really do need some assistance here.

Well, if you're a programmer as you claim, how about showing how you would solve it in *YOUR* programming languages of choice. That'll prove that you're just not some dude hoping for someone to solve their homework for them. This forum is always glad to help fellow programmers, if they show some effort in solving problems themselves.

When I picked up Perl some 11 years ago, I took a good tutorial on the Internet. After having worked for 3 or 4 hours on this tutorial, I was certainly able to do the task you've described (probably not the best Perl practices, but something working and doing what was needed), except possibly the sorting.
I really suggest that you or your son give a real try.
