Please could someone tell me how to use a single-dimensional array as a
two-dimensional array? Is the following correct:
int ROW_SIZE = 5;
int COL_SIZE = 3;
int *arr = (int*) malloc(sizeof(int) *ROW_SIZE*COL_SIZE);
arr;

After reading all the FAQs, I cannot solve the following problem:
I have a pointer of type double. I am supposed to
1) Allocate memory for it assuming that the pointer will be pointing
to a multi-dimensional array whose dimensions will be specified at
run-time.
2) Set the individual elements of the array using pointer-arithmetic.

Hi!
I am wondering if someone can point me to the needed sort function. There are so many of
them that I simply got lost by reading their descriptions. I try to explain what I need.
I have a multidimensional array and I have a function that outputs it as a table.
$arr contains an array that contains usernames
$arr contains an array that contains real names
$arr contains an array that contains e-mails

I have a "population" of objects that is suppose to do a lot of stuff during its lifecycle... I had everything working fine (not fancy code, though) with an array, but now I've received instructions to let the population change size over generations. This means my array no longer works...I want to change it to a vector (or map), keeping the basic structure of the code. But it beats my skills...I read a thread...

I am still having a problem understanding K&RII on p 112. I have
looked at the FAQs --which I am sure answer it in a way that I have
missed, so here goes.
A 2-dim array, (per K&R) is really a 1-dim array, each of whose
elements is an array.
Looking at the debugger I use, arr is shown as an initial value
of "2", but when expanded, there are 2 consecutive arrays of 13
elements.
So, may I ask this?
Is there anything special that marks the...

The subject might be misleading.
Regardless, is this code valid:
#include <stdio.h>
void f(double *p, size_t size) { while(size--) printf("%f\n", *p++); }
int main(void) {
double array = { { 3.14 }, { 42.6 } };
f((double *)array, sizeof array / sizeof **array);
return 0;

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...

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.

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...
