Ok, I'm quite a newbie, so this question may appear silly. I'm using
g++ 3.3.x.
I had been taught that an array isn't a lot different from a pointer
(in fact you can use the pointer arithmetics to "browse" it). So I
expected that when I run this program, I get both c1.A and c2.A
pointing to the same address, and changing c1.A means that also c2.A
changes too.

Hi,
I need some help in declaring an array of pointers to array of a
certain fixed size. I want the pointers to point to arrays of fixed
size only (should not work for variable sized arrays of the same type).
eg:
int arr1;//Array of 20 ints
int arr2;
int arr3;

Hello all,
I was wondering if there were some sort of limitations on the "if"
statement? I'm writing a program which needs to check a bunch of
conditions all at the same time (basically). And I'm pretty sure the
rest of the program is working just fine. The only thing I could think
might be wrong is that the if statement can only hold so many values in
itself? Let me show what I'm doing:
if (table001]>>5]&b&0x1f] != 0 &&

All this time I was under the illusion that I understand the concept of
multi-dimensional arrays well ---- however the following code snippet
belies my understanding.
I had assumed all along that a declaration like:
int intArray
means that there is an array of pointers to int with a size of 5, each
of whose elements is an array of int with a size of 3.
This definition seemed intuitive to me since a declaration like

Hello,
I am attempting to separate a two dimensional array into two
one-dimensional arrays through a function. The goal of this is that,
from the rest of the program, a data file consisting of two columns of
coordinate data is read and stored into a 2D array. From this 2D array
I would like to split it into two 1D arrays, consisting of x and y
components, respectively. However, to return the two arrays from the
function I am...

Hi,
I am trying to pass a function an array of strings, but I am having trouble
getting the indexing to index the strings rather than the individual
characters of one of the strings.
I have declared an array as:
char *stringArray = {"one","two","three","a"};
When I pass the array using:

I am writing a game and I am having a challenge with my combat
function. All I want to do is find out how to group pieces that are in
the same space. There are two sides and all the units that are in the
same space fight. I want to add up the attack factors and defending
factors in the same space then figure out the odds so I can roll
against an odds table. Basically each piece holds its own x and y loc.
Here is what I have right...

Hello,
I have a question about what kind of datastructure to use. I'm reading
collumn based data in the form of:
10\t12\t9\t11\n
24\t11\t4\t10\n
.....
I now have a structure which allows me to access the data like this:

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
