Hi all:
I have a question about memory allocation to an object of a class.
For example, I define the following class:
class example_class{
public:
example_class();
void funtion_1();

I am having lots of trouble getting a simple program that initializs a
dynamically allocated 2D array to work. My 2D array is not getting
initialized properly, and additionally I am getting a "Null pointer
assignment" error. Kindly help.
Also, eventually I intend to move this logic to a separate function.
For that, I believe, that I will need to pass a
pointer-to-pointer-to-pointer type as an arguent. Please confirm.

Hi
I have a 2 dimensional array allocated as a contiguous chunk of
memory, as described in Question 6.16 in the FAQ (i.e. in the manner
of array 2 on the page http://www.eskimo.com/~scs/C-faq/q6.16.html).
I have a function declared as func(..., array,...) and I wish to
pass my 2D array to that function. As I understand it, this should be
allowable since the 2D array is contiguous in memory, and if i
therefore call it as func(...,...

Hello, hello.
So. I've read what I could find on google(groups) for this, also the faq of
comp.lang.c.
But still I do not understand why there is not standard method to "(...)
query the malloc package to find out how big an allocated block is". (
Question 7.27)
Is there somwhere explained why - because it would seem to me, that free()

Hello. I have a small C# program which uses a number of large arrays of
double. The program runs fine on my desktop PC which has 2 GB of memory, but
when run on my laptop with 512 MB the laptop practically freezes up, from
running out of memory. I would therefore like to modify my program so that
memory space used by the various arrays can be freed up once I am done with
each array. I have tried many things before calling GC.Collect(),...

This question has been posted to this forum before and I read the
thread but found that the answers were perhaps imcomplete, so I am
trying again.
Whenever I am creating objects I would like to keep track of the
memory which is used for each object (for stats purpose). They are 2
basic approaches, one is to write a Memory manager type of class where
new & delete would be overloading the standard new & delete operator.
Each time the new...

Hello everyone, this is my first thread in this .NET forum.
Since I am studying C#.NET in this semester, I reckon this would be just the right place for my asking questions regarding the C# language and the .NET framework:)
I got some experience of ANSI C where you declare an array in stack, so:
int myArray;
would allocate a continous piece of memory in stack which can contain 10 integers in total.

Can a class has a member array which will be dynamically allocated during runtime? Such as
double* A=new double
here n is an integer member variable and will be determined during runtime and the class will have the array *A allocated.
Thanks in advance.

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,...

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...
