Standard exception classes in C++ have what() which returns const char
* and
they have constructors accepting string.
Where is that string created and when is the string destroyed?
In the function below, e is a local object so when the function
terminates,
the internal string should be gone too, isn't it?

Hello out there.
sometimes I need to have proper control of the floating point arithmetic of
the C(and C++) runtime system, and using the f.p. exception handling of the
C99 standard is quite handy for that purpose. The only problem when dealing
with f.p. exception signals is that there is (afaik) no specification *when*
the f.p. exception is raised, with one notable exception:
'feraiseexcept(int)' raises the exceptions passed in the...

Hi,
a strange behaviour when working with exceptions :
when I divide and integer by 0 will an exception be thrown. OK
but, when I divide a double by 0 is no exception thrown ???
How come ?
Try it out.

Hi there,
Not sure if any one has experienced this before and can tell me what's
wrong with this statement:
if verified = false then dataObjects.HasError = true
This is all on one line and verified is defined as a boolean variable.
Irrespective if verified is set to true or false in ALWAYS executes

Hi all,
I am a bit perplexed by the following behaviour of the 'is' comparator
False
True
My understanding was that every literal is a constructure of an object.
Thus, the '2.' in 'x = 2.' and the '2.' in 'x is 2.' are different objects.
Therefore, the comparison yields false.

The simplicity of stack unraveling of C++ is not without defective
consequences. The following article points to C++ examples showing the
defects. An engineer aware of defects can avoid hard-to-find bugs.

I'm a bit unsure about exception specifications and the rules that
they enforce.
I've had a look at the C++ spec and it doesn't state about the errors
that it enforces, if an exception is thrown in a function that isn't
specified in its exception specification (assuming there's one
there).
If I compile the code below on Solaris, Linux and AIX, I get the
program coring, causing the "std::exception" to be thrown back to the

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.

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...
