combining two arrays of numbers togethor

Hi

I think this quite simple to do but i am quite new to perl and finding it hard to get my head around how to do this. I think I need to use a foreach function but am not entirely sure.

I have two arrays, each with a column of numbers, I want to combine the two arrays so that I have one array with both columns side by side. I have tried concatenating the arrays but this adds the columns underneath each other as a continuous array of numbers. I would prefer the columns to be side by side in the array.

Any help would be greatly appreciated

Thanks

Hi,

Need a bit more info in terms of what you're data looks like.

Try this debugging so we can see:

use Data::Dumper;
print Dumper(@array1,@array2);

...then view the page, and it should give you the "structure" of the array.

Once we know that, should be able to help you out ;)

Cheers

A snapshot of the two arrays are, i have roughly 4000 enteries in both arrays.
@endsite=
2796
3730
5017
9188
9890

@startsite=
2801
3734
8238
9306
12163

and I need it to look like

@combined=

2796 2801
3730 3734
5017 8238
9188 9306
9890 12163 ####So the data is organised into two columns in one array

I hope this makes more sense

Hi,

Try this:

Code:
for (my $i = 0; $i <= $#endsite; $i++) {  
	print qq|$endsite[$i] $startsite[$i]\n|; 
}
