I've been struggling with this question for a while. What is better
design? To design functions to return error codes when an error
occures, or to have them throw exceptions.
If you chose the former, i have a few questions that need to be
answered.
1) What about functions that need to return a value regardless of the
error. How can they also return an error code unless the function has
"output" parameters. This seems messy and...

People say that is a bad technique to throw exception from
constructors; and that the solution would be to create a function
_create_ to initialize an object.
What about copy constructors? How can we avoid throwing exceptions? If
we already have an abject witch was initialized wit _create_ we will be
forced to call create in copy constructor and to throw exceptions from
it.
Have a nice day,

Is it appropriate to throw exception from a constructor?
Thats the only way i could think of to denote the failure of
constructor, wherein i am invoking couple of other classes to
initialise the object.

I have a class that throws exceptions in new initializer, and a static
array of objects of this type.
When something is wrong in initialization, CGI program crashes
miserably. Debugging shows uncaught exception.
How to catch an exception that happened before main() try { ... }
catch (...) { ... } block?
Is there a way?

I wrote some sample code (see below) for nested exception throwing
i.e. my catch blocks are throwing exceptions of their own (for
simplicity I used standard exceptions). I am getting some extraneous
characters (St9) in my final output. Can anyone kindly help me
interpret that please?
Thanks,
Ramesh

Hey all, this might seem somewhat remedial but I'm unable to find any documentation on it - it pertains to throwing exceptions within a DLL.
I've written a DLL that contains a bunch of classes. One of my methods validates the contents of a file and throws any necessary exceptions based on invalid content - I'm using a standard "throw new exception..." call ...the thing is, when my code reaches the line where the exception is thrown, my...

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
