Hi all,
I didn't find this explicitly stated in the FAQ so I wanted to verify
it.
A class and a struct are the same except for their default access
levels, right? So then, if I wanted a member pointer in my class to point
to an int in a struct I would have to declare the member pointer to be:
class MyClass

I know how to write "Pointer to Function" inside struct or class without
using static, but I have decided to add static to all functions inside
struct or class because I want member functions to be bound inside struct or
class to become global functions. It makes easier for me to use
"struct.memberfunction()" instead of "globalfunction()" when I have to use
dot between struct and member function rather than global function.
I do not have...

When I'm reading from or writing to a network socket, I want to use a
struct to represent the structured data, but must use an unsigned char
buffer for the call to sendto() or recvfrom().
I have two questions:
1. Is it generally safe to "overlay" the structure on the buffer,
e.g.:
unsigned char buffer;

Hello
I have received a lot of help on my little project here. Many thanks.
I have a struct with a string and a long member. I have worked out how to
qsort the struct on both members. I can do a bsearch on the long member
(nKey) but I am struggling to do a search using the string member.
The code I am running appears below. It doesn't crash or anything. It is
just that when I do the last bsearch using "192.168.1.3" I SHOULD find...

I would like to check if I understand the following excerpt correctly:
6.2.5#26 (Types):
All pointers to structure types shall have the same representation and
alignment requirements as each other. All pointers to union types shall
have the same representation and alignment requirements as each other.
Does it mean that *all* structure (or union) types have the same
alignment?
Eg. type

Hi,
I'm trying to solve a programming lab assignment for my college C
programming course, but as they taught us two semesters of Java before
teaching us any C, I'm having problems with all the aspects of
pointers. I'd appreciate if anybody could help me with the following
problem:
I tried to learn how to use malloc, free, and the * and & operators.
I started with a few simple lines of code like:

The following code snippet shows that VC++ 7.1 correctly compiles a static member function invocation from an Unrelated class, since this static member function is public. I expected to compile the same invocation from a DistantlyRelated class. What actually happened was that the compiler produced:
error C2247: 'A::function' not accessible because 'CloselyRelated' uses 'private' to inherit from 'A'
I'm guessing that the above compiler...

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
