hi
in java i found that when a method has a throws clause in the definition,
callers must either handle the exceptions thrown by the method they are
calling or "forward" the exception to the caller by specifying a throws
clause as well.
is there a similar machanism in c++? i want to force a developer to write
handlers for all possible exceptions a method of my class library can throw.

I'll be the first to admit, I'm not entirely clear on the appropriate
usage of either.
From what I am reading in my books, a Struct and a Class are pretty
much the same, with the difference being, a Class can have private and
protected members, but a Struct everything is Public by default.
I laymans terms what would be an appropriate reason to choose a Struct
over a Class?
So why would one want to choose a Class over a Struct.

Hi All.
I have a question regarding Herb Sutter's idiom of implementation of
operator= via nonthrowing swap() member function, to guarantee strict
exception safety.
The idea of the idiom is shown by the example:
-- code fragment 1 ----------------------------------------------------
class MyClass

Hi all. Just working on a small virtual machine, and thought about using
vector iterators instead of pointer arithmetic. Question is, why does an
iterator plus any number out of range not generate a out_of_range exception?
Maybe this is a gcc issue?
I'm using gcc version 3.3.3 (cygwin special).
Here's the full sample code:
#include <iostream>

Greetings!
I am working on an application that targets a Pocket PC running Windows CE
and SQL Server CE. Almost all functions in the application use a Try block
with a Catch block that looks like this:
Try
TryToDoIt()
Catch e as Exception
LogTheError(e)

Hi,
I am in need of a deep copy smart pointer (Boost doesn't provide one)
which doesnt require the contained types to have a virtual copy
constructor. I wrote a smart pointer class that I think meets these
requirements, but after reading the chapter on exceptions in
'Exceptional C++':Sutter, I am not sure if its is really Exception safe
or Exception Neutral. I suppose putting the theory in that chapter into
practice isn't trivial.

Hello -
I have a problem where I need to test some numeric code using a
variety of built-in integer types:
obj_type1 = obj_type2 OP obj_type3; // is obj_type1 correct?
If I test with 10 built-in integer types, then I get 1000 permutations
of the above statement. If I then test a dozen different operators, I
get over 10,000 test operations.

I have a set of classes, cell, cell_body, and cell_internal.
cell_internal is an abstract base class, intended to encapsulate
deferred computation.
cell is just a wrapped pointer around cell_body; this is the user's
interface to this code.
When a cell is created, it creates a cell_body and attaches a
shared_ptr member (value_) to the body. This shared_ptr should never
be changed; the cell can only have one cell_body during its...

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...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
