Hi All,
Sorry if this is off topic, but I could not seem to find a suitable OO
Design newsgroup. If there is one feel free to let me know.
Here is a simplification of a general design problem I face.
Say you have:

the requirement is :
Create a class called Rational (rational.h) for performing arithmetic with
fractions. Write a program to test your class.
Use Integer variables to represent the private data of the class – the
numerator and the denominator. Provide a constructor that enables an
object of this class to be initialized when it is declared. The
constructor should contain default values in case no initializers are
provided and should...

Is there any way to add an embedded resource to a project without copying it
to the project's directory? I have shared resources and don't want each
project using the images, xml files, etc. to need to be updated with the
current copy before being built. I also don't want projects being built with
the old copy.
Thanks!

Trying to figure out the technique which should be used
to add rows to a datagrid. I am thinking that I would
want an "Add" button on the footer, but I am not quite
sure how to do that. Is that the best method? Do you
have a sample of how to do this?

Hi all,
I have written a small ProperCase function which I would like to make
available to our team at work through our common class library.
A colleague mentioned that I could write a new class which derived from the
String class, add the function there and then we would all use the new class
which contained my function and all of the others etc....sounded relatively
straight forward...

I'm wriiting an MFC C++ application which uses a third party C# .NET API via
a DLL. The app runs fine. If I add a new, empty C++ class, and compile/link
it refuses to run, complaining about not being able to load an assembly.
Removing the class from the project and doing a rebuild all gets it working
again. Its as though I've hit a threshold? Any ideas?
- I'm using Visual Studio 2005
- Although my code is MFC native C++, the third...

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...
