Good evening everyone, I'm back :)
Let me explain my problem. I have a hashtable in wich I store the products a costumors buys (%orders). It uses the productcode as key and has a reference to an array with the other info as value.
At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items)
This is how I do this:
sub rewriteInventory{
open(FILE,'>inv.txt');
foreach $key(%inventory){
print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n"
}
close(FILE);
}
where $inventory{$key}[x] is 0 - Title, 1 - price, 2 - quantity.
The problem here is that when I look at inv.txt afterwards, I see things like this:
CD-911|Lady Gaga - The Fame|15.99|21
ARRAY(0x145030c)|||
BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12
ARRAY(0x145bee4)|||
Where do these "ARRAY(0x145030c)|||" entries come from? Or more important, how do I get rid of them?
This is the last part of this school task, I had so much problems programming all this and this stupid little thing comes up now and I'm really fed up with this whole Perl thing. (this aside :p)
I hope someone can help me :)
