Hi all,
I recently came across the following code:
// some data
struct Data { // ... some data };
// a list to hold the data
vector<Data> dataList;

I have the following code, where good_list is a vector of CUnits:
int high_cutoff = 10;
vector<CUnit>::iterator it;
for (it = good_list.end(); it != good_list.begin(); --it) {
CUnit* ccu = it;
if (ccu->GetCutoff() >= high_cutoff) {
good_list.erase(it);
}
}

vector<int> v;
erase() requires (as input parameter) and returns vector<int>::iterator,
rbegin() returns vector<int>::reverse_iterator.
So, a compiler doesn't accept v.erase(v.rbegin()).
Do we have to write v.erase(v.end() - 1)? Or there exists something else?

I have a vector from which I want to erase elements between iterators i,j.
If i<j, everything works as expected, but if j>i, an insertion is actually
performed. Example:
vector<double> x(10);
vector<double>::iterator i=x.begin()+2, j=x.begin()+6;
x.erase(i,j); // i<j, ok, erases 4 elements.
x.erase(j,i); // j>i, no error, just inserts 4 elements.

For discussion purposes, assume the vector ivec contains 67108864 (67
million elements) elements. Lets futher assume nstart and end equal
1008000 and 11088000 respectively.
The question. What's the _fastest_ way to erase element numbers less
than 1008000 and element numbers greater than 11088000. Current
approach.
typedef std::vector < int INT_VEC ;

I am facing problem while erasing an elemet from stl vector when its
size is 2. It works fine when SIZE 2.
Can anybody help me in this?? Following is the sample code which i
tried.

suppose I will delete an element pointed to by "iter".
like this:
vector<ints;
for(vector<int>::iterator iter=s.begin(); iter!=s.end(); iter++){
if(*iter==3)
s.erase(iter); //A
}
in line A, if element by "iter" is erased, will "iter" point to the

If we call,

this invokes undefined behaviour.

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...

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...
