Hello,
I have a function that generates some values (e.g. vertices in 2d space)
the number of which I dont know. So, it could generate 20 vertices, 100
vertices, or even 1 vertex.
void generateVals()
{
.....
//generate some values

Hey all,
Can someone help me figure out how to pass a dynamic array into a function?
Its been giving me some trouble, and my textbook of course doesnt cover the
issue. Its probably something simple, but its just not popping into my mind
at the moment.
My little snippet of code is below. Basically, the studentID array is
dynamic so it will fit any length of a Student's Name. What I'm trying to
do is place this chunk of code into a...

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);

The latest project in my ongoing quest to evolve my brain from Pascal to C
is a simple word game that involves stringing together random lists of
words. In the Pascal version the whole array was static; if the input
file contained more than entries, tough.
This time I want to do it right - use a dynamic array that increases in
size with each word read from the file. A few test programs that make use
of **List and realloc( List, blah...

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

Hello!
Can someone explain to me the difference between dynamic
array of pointers vs dynamic array of objects by giving a
real life example. Following is the code that I am using
for dynamic array of objects. I am skipping initialization
and other member functions.

Using VS2005, I dynamically create an event delegate. Code follows question.
My method gets the event's parameters and passes them onto a common event handler. My delegate gets called when expected and in turn, calls my common event handler. However, once in the common event handler code, the "this pointer" is wrong and hence I can't access other class properties and methods.
Even if I invoke the dynamic method directly, the "this pointer" 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,...

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...
