This is sort of my first attempt at writing a template container class, just
wanted some feedback if everything looks kosher or if there can be any
improvements. This is a template class for a binary search tree. Note there
is a requirement for this to be a Win32/MFC "friendly" class, thus the use
of CObject and POSITION. There is also a requirement for there not to be a
separate iterator class.

I am trying to find a way to eliminate vararg functions from my code
by packaging the input parameters in stringstreams. Here is an
oversimplified example of what I am trying to do:
Functions FUNC1 and FUNC2 delegate to functions func1 and func2,
respectively. The goal is to delegate to func1 and func2 using an
identical interface provided by the template function
template<typename F>FTEMPL that takes a stringstream as input and...

Hello,
I want to build a library to help exporting c++ functions to a
scripting languagge. The scripting language provides a function to
register functions like:
ANY f0()
ANY f1(ANY)
ANY f2(ANY, ANY)
ANY f3(ANY, ANY, ANY)

I have a class which needs to accumulate data. The way we get this data
is by calling a member function which returns float on a number of
different objects of different type (they are all the same type for a
given instance of the class, but different types for different instances.)
#include<set>
using namespace std;
template<class T>

I have the following code segment - which compiles fine. I'm just
worried I may get run time probs - because it looks like the functions
are being overloaded by the return types?. Is this Ok: ?
template <class T1, class T2>
int getValue( T1 col, T2 row ) ;
template <class T1, class T2>
double getValue( T1 col, T2 row ) ;

Greetings!!
I introduced the so-called "thin-template" pattern for controlling the
code bloat caused due to template usage.
However, one of the functions in the template happens to be virtual as
well. To support thin-template, I need to make virtual function as
inline.
Now, I know that compiler would generate an out-of-line copy when it

I am having a very strange problem involving virtual
functions in template classes. First of all, here is an
extremely simplified structure of the two classes I am
having problems with.

base& operator/=(const base&);

Diehards,
I developed a template matrix class back around 1992 using Borland C++ 4.5
(ancestor of C++ Builder) and haven't touched it until a few days ago. I
pulled it from the freezer and thawed it out. I built a console app using
Microsoft Visual C++ 6 (VC++) and it worked great. Only one line in the
header file had to be commented out.
I built a console app using Borland C++ Builder 5. The linker complained of
references to...

Hey all,
I've been running into a problem with default values to template'd
functions. I've boiled down my problem to this simple example code:
#include<iostream>
using namespace std;
// function object

This is from a thread that I posted on another forum some days ago.
I didn't get any response, so I'm proposing it in this ng in hope of
better luck :)
The standard explanation is that pointer to functions are hard to
inline for the compiler, and so you won't be able to avoid function
call overhead.
This is an important aspect when you are calling a function very
frequently for evaluation reason: think of the problem of performing...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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...
