I could see that it is possible to have hash array using objects like
var hash = {"a" : "1", "b" : "2"};
Couldn't still findout how to declare hash array in Array.
var arr = new Array("a" : "1", "b" : "2"); doesn't work. Any hints? TIA

Or why I just did myArray = "Computers" but myArray.length is
showing 0. What a hey?
There is a new trend to treat arrays and hashes as they were some
variations of the same thing. But they are not at all.
If you are doing *array", then you have to use only integer values for
array index, as it was since ALGOL.

A while ago I proposed to update info in the group FAQ section, but I
dropped the discussion using the approach "No matter what color the cat
is as long as it still hounts the mice". Over the last month I had
enough of extra proof that the cat doesn't hount mice anymore in more
and more situations. And the surrent sicretisme among array and hash is
the base for it.
I summarized all points in this article:...

A question about void*. I have a hash library where the hash create
function accepts functions
unsigned (*hash)(const void *a)
int (*cmp) (const void *a, const void *b)
The insert function accepts a void* key argument, and uses the
functions above to store this argument. It returns something (linked to
the key) that the caller can store a value in. The actual key argument
is always of the same pointer type (as seen in the caller,...

I have ~200 players on a server...
They share the same 512x512 tiles map...
Each player have an explored area and a visible area... visible area is
given by players's current units and buildings...
Now, I'm facing with the problem of how to store does areas...
One way is to keep a explored(512,512) array of booleans... each
explored(i,j)=True mean player explored the tile on (i.j)... the same for

Hi
I am creating a sign-up process on a web site much like that of a
wizard form. I have browsed many sites to look for examples of how to
store the entry data, so that the user can go back and forward along
the sign -up process. I am currently trying to use a Session object to
store all these details and get them back out of session as each step
is selected.
My model was a HashTable of NameValueCollection, so I could go to the

I know this is the wrong way to do it, but maybe someone can tell me the
right way to do it...
I have two different databases that I need to synchronize. The database
doesn't have keys exactly, but it does provide a rowid function.
So, I am storing a dictionary of <string, long>, string being the rowid
and long being a sum of the hash code for each column in the row.
With this dictionary, it is very easy to determine if a row is...

I am writing this program that takes a number gives it a hash humber and then put the orginal number in the array spot.
ex. Enter a number: 32
Hash value is 5 so 32 is placed in the 5th spot of the array. If two numbers have the same hash value my program must insert that number in the next available spot. Here is my code. My problem is I can't make the numbers go in a particular arrray location.
#include <iostream>
using namespace std;...

Hi all,
I want to create an encryption program and started thinking about not
storing sensitive information in the memory since I guess someone
might steal my computer an scan my memory.
So I wrote this method for getting a password from the console and
converting it to an array of bytes for later use in the encryption
algorithm.
The weak point as I see it is the storage of the password - it will be

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...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
