Hello Experts!!
This class template and main works perfectly fine.
I have this class template called Handle that has a pointer declared as T*
body;
As you can see I have a reference counter in the class template so I know
how many references I have to the body. In my case it's the Integer wrapper
class which is the body.
This template works for many different types.
The one that I use is named Integer and is a Wrapper for an int. The...

My undersstanding of using a ref parameter is to be able to pass initialized
value variables as references. Is there any purpose to using a ref paraneter
with a reference variable ? If one does it the compiler accepts it. Does
this mean anything ?

Hi,
Could someone clarify my confusion regarding passing reference types to a
method with ref keyword and explain when it's practical to use it.
It's my understanding that in .NET reference types hold a reference to an
object as opposed to object data itself. So, when reference type parameter is
passed into a method, a copy of objects reference is passed in, so called
method can do whatever to "original" object and a caller will see...

Is there any harm in passing an object into a method with the 'ref'
keyword if the object is already a reference variable? If not, is
there any benefit?

I have the following script:
function Test(){}
Test.F = function(){}
Test.F.FF = function(){}
Test.F.FF.FFF = function(){}
Test.F.FF.FFF.FFFF = function(){}
//var alias = function(){};
var alias = Test.F.FF.FFF.FFFF;

Can you explain why using ref keyword for passing parameters works
slower that passing parameters by values itself.
I wrote 2 examples to test it:
//using ref
static void Main(string args)
{
List<TimeSpantimes = new List<TimeSpan>();
DateTime start;
DateTime end;
for (int j = 0; j < 1000; j++)

Hi,
Form a performance perspective, is it wise to use the ref statement as much
as possible?
Thanks!

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...

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...
