Hi all,
I'm trying to write a generic algorithm routine that will
take begin and end iterators of a container, iterate through
the range and perform a "calculation" of sorts.
The trouble is that the algorithm will behave differently for
the two different types. I've considered calling the algorithm
foo_A and foo_B, but I don't like that approach because it will
blow out in naming complexity down the track.

I am trying to create a vector of type T and everything goes fine until
I try to iterate over it. For some reason, the compiler gives me an
error when I declare
std::vector<T>::iterator iter;
Any ideas why is tihs happening? The code is as follows:
template <class T>
struct StdVectorStorage
{
std::vector<T>* _storage;

Hi,
I want to have a vector like class with some additional functionality
(cosmetic one). So can I inherit a vector class to add the addition
function like,
CorresVector : public vector<Corres>{
public:
void addCorres(Corres& c); //it do little more than push_back
function.
}

I'm moving some code from VC++ 6 to VC++ 2005 and
I've run into a nasty problem because iterators
are no longer pointers.
In the program I'm moving, there's a std::vector
of items hidden inside a class and users of the
class get to iterate it via a const_iterator.
eg.

All,
I need your help understanding why the following code does *NOT*
compile with G++ (tested with gcc 3.x and 4.1.x):
---------------------------------------------------------------------
template<class T>
class myvector { // Just a simplification of std::vector
class iterator {
T a;
iterator &operator++();
};

I am not sure I quite understand the use of iterators. I have this int
array:
int a = {1,2,3,4,5}
I would now like to make an iterator to the first and last element:
std::iterator<intiter;
iter = a;

Hi everyone,
The idea is quite simple: generate a container with random values in
it. For that, I decided to create a class that I called
RandomContainer that inherits from a container (with default value
std::vector<T>). To handle the different ways that the values are
randomized, I created a traits class. The problem that I have, is that
the function randomize() within the traits class takes different
parameters depending on the type...

Hi,
I have the weirdest problem, and I can not see what is going wrong.
I have made a 2d container class, and am implementing an iterator for that class. However, the ++ operator is behaving very strange. The implementation looks like this (there is a lot of code, but I have only included it all for consistency. The problem is quite small and local):
template<typename T> class Row<T> : public std::vector<T> {};
template<typename...

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...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
