I want Foo-type objects to be convertible to Bar-type objects. Can I use
operator Bar() to do this just as I would use operator bool() to convert to
boolean? Example:
class Foo
{
public:
operator Bar() const;
};

Hi, I want to put a type conversion in my class, but I don't want the
conversion to be usable in a passed parameter because it makes no sense.
class cData
{
string s;
public cData(string s)
{
this.s=s;

Ok, starting from the basics. Reference types and value types are all
objects underneath.
So, a String is an object as well.
Now, when when we are debugging and we examine the contents of a String
object - the debugger actually shows the value of containing string object
when you keep a watch on the instance variable.
But when I create my OWN type which holds a string inside - and get this

I want to create several types of double, e.g. D1 and D2.
I want strong typing, such that a function defined for D1 will not
accept a D2 argument.
One solution is:
struct D1 {
double d;
};
However, the usage is cumbersome (I have to access member variable d),

Are there any important differences between the following two ways to
convert to a type?... where 'important differences' means something more
profound than a simple syntax preference of the developer.
x = someObject as MySpecificType;
x = (MySpecificType) someObject;
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...

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...
