Is there an easy way to sort a 2 dimensional array alphabetically by
the second field in each row?
Also, when I use sort() on a two dimensional array, it seems to work a
lot like array_reverse(). Can anyone tell me why?

I need to sort a two-dimensional array. Each day I process a file with 9
comma-delimited fields, and varying amount of records (lines). I want to
pull in each line, split it according to the comma into a two dimensional
array (Perl has it f'r crissake), and sort by one of the fields (Purchase
Order #). Trouble is, Array.Sort only supports single dimension arrays.
Originally I was thinking of making a jagged array, pulling out the Purchase...

With Marshal you can copy data from a one-dimensional array to
BitmapData.Scan0.
What do I do if my array is two-dimensional?
Or, alternatively, can I create somehow two variables
byte arr1; // size 480*640
byte arr2; // size
which are references to the same memory block and allow me to access it
at will with one or two indices, e.g. arr1 or arr2?

Greetings. I'm quite new to PHP and have very little knowledge of
programming in general, so I may be missing something obvious, but I
can't find a solution to the following difficulty in either the PHP
manual or Google.
I have a tab-delimited text file containing numerous lines of data,
which is searched for matches to a query from an HTML form. I want to
be able to sort the resulting two-dimensional array of matches by one
column...

Newbie question here. It's been a while since I've done C programming,
and I hit a wall last night.
Let's say I have a three dimensional array, like so:
int p =
{{{0,0,0},
{1,1,1},
{0,1,0}},

Hi all,
I have a two-dimensional array of data, f.x int's. We can imagine that
the array is "really large". Now I want the data in it and store this
in a one-dimensional array.
The obvious way to do this is a nested for-loop - but we all know
O(n^2) is bad. So I am looking for something like ArrayList.ToArray(),
or Matlabs A(:).
C#

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
