I am having a little trouble with dynamic memory allocation. I am trying to
read a text file and put the contents into a dynamic array. I know I can
use vectors to make this easier, but it has to be done using dynamic arrays.
I don't know the size of the text file ahead of time, though, so I created a
class that includes a method to resize the array. Here is that class:
class Data
{
public:
Data(int initialsize);

Hi Everyone,
I apologise if this is covered in the FAQ, I did look, but nothing
actually stood out to me as being relative to my subject.
I want to create a 2 dimensional array, a 'array of strings'. I already
know that no individual string will be longer than 50 characters. I just
don't know before run time how many elements of the array will be needed.
I have heard it is possible to dynamically allocate memory for a 2

I have written the following program using VS2005. The program is a Dynamic
Array similar to System.Collections.ArrayList in .NET. The program works
okay until I reach 65536, I can't seem to figure out why, as it seems my
logic is working okay. I am a .NET programmer so I am not used to dealing
with un-managed C++ code. Please criticize my code if you think it is poorly
written.
This is the loop from main() that will blow up the program...

Hello all!
Perhaps the most important feature of dynamic polymorphism is
ability to handle heterogeneous collections of objects.
("C++ Templates: The Complete Guide" by David Vandevoorde
and Nicolai M. Josuttis. Chapter 14.)
How to implement analogue of this technique via static polymorphism?
Perhaps there is special design pattern for this purpose...

I need (okay, I want) to make a dynamic array of my class 'Directory',
within my class Directory (Can you already smell disaster?)
Each Directory can have subdirectories so I thought to put these in an
array. The application compiles but aborts without giving me any useful
information.
What I suspect is happening is infinite recursion. Each Directory
object creates an array of Subdirectories each of which has an array of...

hi guys please help about Linked List,
I'm having trouble freeing the allocated memory of a single linked list node with a dynamic char* fields, it doesn't freed up if I use the FREE() function in C.. But if I try to use a single linked list with a static char array fields I can free the memory allocated with out any problems using the FREE(). So, why freeing a single linked list with dynamic char* is hard and why the FREE() function is...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
