HI, I am a little confused about char * and char.
How would I be able to return a char* created in a function? Is new() the only way? How would I be able to return a
point and a value at the same time? I thought of a possible solution. However, I am not quite sure if I understood
char vs. char*. Any insight is greatly appreciated.
Here is the question:

Dear all,
I did the following analysis to conclude that the following pointer
types are not compatible. Please let me know If my analysis and
interpretation of the C standard are correct:
const char * : "pointer to const-qualified char".
char *: "pointer to char".
Are these pointed-to types compatibles?

child class, and my driver.
All that is suppose to happen is the user enters data and it uses
parent/child class to display it.
here is the 4 errors.

Hi,
This is a very simple question but I couldn't find it in your FAQ.
I'm using VC++ and compiling a C program, using the /TC flag.
I've got a function for comparing two strings

Hi all,
I've been working on this code since morning and seems like I need stronger skills on pointers n arrays.
I'm trying to read the content of a config file, which has x lines and then pass it to an array of characters.
Not really sure if I did use the strtok function correctly, but here's what I got so far..
#include <stdio.h>
#include <stdlib.h>

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

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...
