I have a std::vector<int> which, after some initialization, has a
fixed number of elements...after initialization I must do the
following repeatedly: I remove an element which could be anywhere in
the vector, and add another element which will always be at the end,
ie.
vector<int> v;
int i, x;
.... initialization

What is a good way of removing elements from std::vector so that the
elements removed satisfy a predicate and end up stored in another
std::vector. It seems as though the algorithm std::remove_if only achieves
half the job. Here is how I would use std::remove_if to remove elements from
std::vector based on predicate:
v.erase(std::remove_if(v.begin(), v.end(), pred), v.end());
After that line is executed I cannot get back the elements...

Hi all,
I'm trying to clean up the output from Word that has been
pasted into a textarea. I'm purging much of the html (all
styles, attributes etc) and would also like to remove things
like vector graphics. To do this I want to simply drop all
elements (or their children) which are in any namespace other
than the default: all the microsoft-specific o:p, v:drawLine, etc
tags. But I can't persuade javascript to even see the namespaces!...

Hi All,
I was wondering if somebody could tell me if there is an efficient way
to do the following. Say I have a list(or vector) A and a list B, I want
to remove any elements in B, that are also elements in A.

According to MSDN, removing elements invalidates only those iterators
that had specifically pointed at the removed elements.
But I tried following codes, and find that without the repeated
it=map_.begin();
there will be memory violation.
So, the iterator IS invalidated even if it's not the removed one.
why?

I cannot relieve that I am working on Thanksgiving, but I am stuck over
something that should be simple. I have a vector that has twenty-four
elements. I need to remove the four elements whose positions equal
zero. The code below only removes two of the four. Any ideas?
logfile << "\n\n\n. . .removing flat positions";
logfile << "vector size=" << componentPerformance.size() << endl;
int position=0;

Hello, I have a list of elements and I want to perform an operation on a
subset of them and then remove them from the list.
If I build a sequence of elements via LINQ to drive the enumeration, as soon
as I remove the first element the enumeration operation is broken.
This surprises me. I thought the LINQ'd sequence would be its own
collection, impervious to changes in the original source collection.

In a library I am writing, I wish to stop people from removing item's from an List<> collection, is there an alternative or a way of overloading the Remove method that would stop other developers removing elements?

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...

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...
