Can I specialize a template function in a subclass without overriding
it? (the main template function is defined in a base class).
Now I'm doing something like that:
(in base class)
template<class X>
void myfunc(X par1) { }
(in derived class)
template<class X>

Hi, all.
When reading C++ books, I'm alway confused by those terms "redefining
functions", "overloading functions" and "overriding functions".
Please give me some comments on those terms. Thanks.
If giving more strategy hehind them, more helpful.
Best Regards,

Hello everybody,
I'm new to C++ (I have some C background). I've read up on this topic a
few times but it just dosen't seem to be sinking in.
1. Whats the difference between overloading and overriding?
2. When is one preferable to use as opposed to the other?
3. How are virtual functions related to this topic
(overloading/overriding) - a real world example of using virtual
functions would be very much appreciated.

I don't get it. What's the main differences between overriding a base
class's methods vs. hiding them?
Thanks,

I have some questions about override in inheritance, and virtual members.
I know that you can you override a method by two ways in C#, one, is
overriding with the new keyword, like:
public new bool Equals(object obj) {}
Another is using the override keyword, like:
public override bool Equals(object obj) {}

I am confused about the purpose of 'new' in overriding.
Consider following example.
<code_snippet>
using console = System.Console;
public class TestClass
{
public static void Main()

What is the purpose of hiding intead of overriding a method? I have googled
the question but haven't found anything that makes any sense of it.
In the code below, the only difference is that when the Poodle is upcast to
the Dog (in its wildest dreams) it then says "bow wow" where the bernard
always says "woof" (see code). Basically, it appears that I'm hiding the
poodle's speak method from everything except the poodle.
Why would I...

Any thoughts on how a method on a base class can be prevented from
being overriden or hidden?
Basically the idea is that no matter what all derived classes should
use the method in my base class. Got to prevent hiding via the new
keyword as well.

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...

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...
