Haiku generator

Hello, fellow monks. This is my first original program and it is a basic haiku generator. I got the idea because we are doing poetry in school and I saw the poem thing by zentara and thought it would be cool.

use strict;

my @line1 = ('annoying sensei',
         'oh, young grasshopper',
         'dis-honourable',
         'you aburi brain'
            );

my @line2 = ('learn to run before you walk',
         'he thinks he knows everything',
         'insubordinate pupil',
        );

my @line3 = ('hey, wait a minute',
         'he must be senile',
         'he will face my wrath',
         'his brain is not well'
            );

print $line1[rand @line1], "\n";
print $line2[rand @line2], "\n";
print $line3[rand @line3], "\n";

Seeing as this is my first program, if anyone could give me some pointers, that would be uber.

if anyone could give me some pointers, that would be uber. Whenever you catch yourself typing the same expressions more than two times, give it a break and think: "Can I somehow express this in a loop?". In this case the outcome of such a thought would look like this code. `use strict; my @haiku = ( [ 'annoying sensei', 'oh, young grasshopper', 'dis-honourable', 'you aburi brain' ], [ 'learn to run before you walk', 'he thinks he knows everything', 'insubordinate pupil', ], [ 'hey, wait a minute', 'he must be senile', 'he will face my wrath', 'his brain is not well' ], ); for my $line (0..2) { print $haiku[$line][rand @{$haiku[$line]}], "\n"; }` [download] Here we have a data structure (array of arrays) that holds your haiku strings. Once we have that we can easily loop over the main array an choose a random line from each "sub-array". See perlref and perlreftut for more about data structures. holli, /regexed monk/	[reply] [d/l]

But then, why not just iterate through the array directly? `use warnings; use strict; my @haiku = ( [ 'annoying sensei', 'oh, young grasshopper', 'dis-honourable', 'you aburi brain' ], [ 'learn to run before you walk', 'he thinks he knows everything', 'insubordinate pupil', ], [ 'hey, wait a minute', 'he must be senile', 'he will face my wrath', 'his brain is not well' ], ); for my $line (@haiku) { print $$line[rand @$line], "\n"; }` [download]	[reply] [d/l]

Hey ambrus, thanks for the advice but I'm new so I haven't learned loops yet. Thanks for the help. SOA, DOA, GOA, whatever, hypknotizzed	[reply]

Hey holli, thanks for the advice but I'm so new I haven't even learned loops yet. I guess I should get started on that... SOA, DOA, GOA, whatever, hypknotizzed	[reply]

If you managed to do so much with so little knowledge you must be well suited to perl. Arrays are some sort of 'loops' in a linear way... <updated>Ouch!,thank you. `print("$_ \n") foreach (qw(this is a loop of words));` [download] Landlords production is only eaten by landlords...
