Hi.


I'm trying to create an array of nodes. In C I would typically make an array and fill it with instances of a "struct" structure. How can this be done in perl?

Take a look into "perllol" and "perlref" - you can have either an array (index by number, has a range) or a hash (index by key which must be something which leads no matter how perlish you might get there to something string-ish in the end, no range).

Into both you may put more or less anything - especially references (you're possibly more comfortable with "pointer" here) to: other arrays or hashes, to named or anonymous functions, to filehandles...

You don't need to declare size or data type of the content in advance and either hashes and arrays will grow as you go and add elements.

Both list types come with a set of functions to manipulate them (adding/substracting elements, deleting, checking for existence..) and most perl loops are list-aware and support some sugarcoating for easier access.

Wether you need an array or a hash, you'll have to decide.

And here's the tutorial: http://perldoc.perl.org/perldsc.html

Thanks for the advice.

I ended up putting hashes in an array, which worked out fine.
