When running the following code:
if (typeCheck.Checked == true && typeList.SelectedItem == "3")
{
return " and wopm3 = '3' or wopm3 = '3C' or wopm3 = '3I'";
}

Hi,
after reading the article " The Standard Librarian : Defining Iterators
and Const Iterators" from Matt Austern:
http://www.ddj.com/showArticle.jhtml;jsessionid=41JODBZDWEMBYQSNDLOSKH0CJUNN2JVN?articleID=184401331
I wanted to test using the non-template function friends of template
classes. So I devised this code:
===8<======8<======8<======8<======8<======8<======8<===

I am getting a compiler error that I can't well explain or even
understand the origin of (though I boiled it down close...). Below is
a bare-bones example.
What I am doing is defining the increment operator in a class and then
defining a derived class and using the derived class. When I try to
use the increment operator on an instance of the derived class (as an
instance of the derived class, not when used as an instance of the base...

Compiler - gcc 4.0 (XCode)
I'm *extremely* new to C++ (but have extensive experience with Java),
so please go easy on me.
I'm running into a very odd situation which I believe is related to
template instantiation. I need to include a header file from a library

Hello,
I have a doubt about this operator, and I haven't found the answer in
internet (yet).
When calling the operator << several times in an expression, are all
parameters evaluated first and then passed to cout::<<, or are being
passed when they are evaluated ?
An example to clarify my question :
int foo()

How is an output stream operator of a class nested in a class template
defined? The code fragment below does not compile. Maybe it's just me,
but I don't see why it should not compile.
Best regards,

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,...
