1 - it's trying to match the regular expression on the line starting `$string =~ ...` against the string found on the previous line. 2 - I'd start with `#include <stdio.h>` and `#include <stdlib.h>`. Maybe I'd also have `#include <sys/types.h>` and `#include <regex.h>`. I wouldn't start with `#! /usr/local/bin/perl`, and I definitely wouldn't start with `#! /usr/local/bin/perl5.003 -w`. I think the C preprocessor would take deep offense at either of those. Finally, I'd get on to reading my course material. Most of my professors asked questions right out of the course material. When I finally figured that trick out, it was my last year, and my GPA shot way up.	[reply] [d/l] [select]

I wouldn't prototype in Perl. By the time you've typed enough characters in Perl to look like you've done some work you have completed the task. That's not prototyping, that's implementing. Were I you I'd take a look at perlretut Perl is Huffman encoded by design.	[reply]

If your problem was that urgent then reading the Perl manual pages or the textbook for your course would probably be far more effective than posting a request on a web site. We don't tend to respond well to urgent requests for homework help around here. Perhaps you'll find YAPE::Regex::Explain to be interesting and/or useful. -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

Wow, this smells a lot like homework. Or worse, a test question. Retitled by holli from 'Re: Quick reply needed'.	[reply]

Yep clearly a homework or test question. However from the questions, I think the professor is an idiot. Q1 - Google it: perl regex As for Q2...What kind of #$@#$!@# idiot would prototype in perl. As noted above just implement it and you're done. This is a good example of why I don't think school is worth the money you pay for it. With dumb profs teaching you to do stupid things you'd be better off getting a job.	[reply]
