I am in the process of reorganizing my code and came across and I came
across a problem, as described in the subject line of this posting.
I have many classes that have instances of other classes as member
variables. So including a forward declaration doesnt help, does it?
Faced with these, I had the following options:
-Include the appropriate header in the header file that contains the
class definition that has a member variable that is...

Is this class evidence of poor design?
class Rectangle
{
double width, height;
public:
double get_width() const { return width; }
double get_height() const { return height; }
void set_width(double width) { this->width = width; }

I have a class that is basicaly duplicated throughout several files with
only members names changing according to the class name yet with virtually
the exact same coding going on.
e.g.

I have a base class, PadRcv, with virtual functions. User code
will derive from this class and possibly supply it's own functions
to override the base class virtual functions. How can I test that
a user-defined class has overriden the virtual function in the
base class?
I have code like this which compiles with gcc 2.95.4:
Attrib Implicits(PadRcv *obj){
Attrib accum = 0;

Hi.
(posted to both newsgroups since I was not sure of which would be
appropriate for this question or how specific to the given language it
is. If one of them is inappropriate, just don't send replies to it.)
I'm making a bignum package for use in a program I've got (this is
something different from the pi program you may have heard about). The
package is going to support manipulating long floating point numbers.

I am into c++ code maintenance for last 3-4 years but recently I am
put into design phase of a new project. Being a small comapany I dont
have enough guidance from seniors.
Currently I am into a situation where I am implementing base class
functions by including a pointer to subclass member in base class.
Reason being functionality is common for subclasses but the members
are common within subclass only (static member of subclass) but...

Hello,
I encountered something unfamiliar to me today and I would like some
clarifications. Unfortunately I don't have access to a standard but
even if I did, I'm not even sure if I could understand it well enough
to answer my question...
Here's the deal: without instantiating the class, the code in question
calls both static and non-static member functions like this:

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.
