My first time working with a PHP class, and after 6 hours of working out the
kinks I am unable to return a value from the class, so now I appeal to the
general audience what on earth did I do wrong this time?
This is the code the retrieves the values:
if (($hasRegistered || $hasPreRegistered) && !empty($uplinenumber)) {
// CHECK TO SEE IF UPLINE NUMBER IS A VALID NUMBER
$regNumberGenerator = new RegNumberGenerator($uplinenumber,...

I'd like to know what goes on under the hood when methods return
objects. Eg, I have a simple Point class with two members _x and _y.
It's constructor, copy constructor, assignment operator and additon
operator (which returns another Point object, and which my question is
about) are as follows:
Point::Point(int x, int y) :
_x(x),
_y(y) { }

I have the following sample program, which can convert function object
with 1 argument into function object with 2 arguments. It can also do +
between function object of the same type.
The last line is very long. I'm wondering if there is any way to
suppress it. I can only think of typedef. But I'm not sure whether I
can use typedef for the return type.
Would you please help me? Please don't be daunted by the length of the
code.

I am trying to verify that I correctly understand something I saw in the DB2
Information Center.
I am running DB2 Personal Edition V8.2.1 on Windows. I came across the
following in the Info Center:
To return a result set from a procedure to the originating application, use
the WITH RETURN TO CLIENT clause. When WITH RETURN TO CLIENT is specified on
a result set, no nested procedures can access the result set.

returned. In the below programme, the function sample()is returning the
value passed to 'k'.
sample(int);
main()
{
int i = 0,j;
j = sample(0);

I'm trying to learn the very basics of using an unmanaged C++ DLL from C#.
This morning I thought I was getting somewhere, successfully getting back
the correct answers to a C++ " int SumArray(int ray, int count)"
Now I'm having problems with C++ "return(false)" being True in C#.
Here is the C# code.

Hello,
I have a BaseClass and many Classes which all inherit (directly) from the BaseClass.
One of the functions in the BaseClass is to (de)serialize the (inherited) Class to/from disk.
1. The Deserialization goes like:

Is it possible to return covariant types for virtual methods inherited
from a base class using virtual inheritance?
I've constructed an example below, which has the following structure:
Shape = base class
Triangle, Square = classes derived from Shape
Prism = class derived from Shape
TriangularPrism, SquarePrism = classes derived from Triangle and
Prism, or Square and Prism respectively

If anyone can help me figure out the what the missing return statements are, I think it might be the fact that I need to add a return false in the getValue()?

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,...
