Dear Friends,
I want to create a hash table using the standard Glib header (if possible) so that I can store a structure and keep the hash key(search key) based on a string.
Any example code would be great since I am not able to get the main idea.
best regards

how would you go about taking a user's input and adding it to a hash?
i'd also like it to permanently add the input to the hash. not just in the ram, add it into the script!

would only print my top value, and not the one I want to "match".... should i not be using if exists? how would you recommend "searching" a hash file...

Hi,
I am not that good at Perl.
But here's what I wanna do.
I want to create a hash where the keys would point to different arrays. This is what I have tried to do but in vain :(
@arr=(1,2,3);
@arr1=(3,2,1);
%hashOfLists=();

Hi,
In Perl, is it possible to use a range of numbers with '..' as a key in a hash?
Something in like:
%hash = (
'768..1536' => '1G',
'1537..2560' => '2G'
);
That is, the range operation is evaluated, and all members of the range are... (3 Replies)
