Hi there,
We have a compiler specific issue which requires us to force template instantiation. This works fine. The problem comes
when I try using std:find() on vector. Since vector has no member function find() and I have to use std::find(). The
linker fails on unsatisified symbols in find().
I think this is because find() is a template function and I have to force instantiation. However, I donot know the
correct syntax of doing so....

Hi,
I am not familiar with for_each very well, suppoase I have a
vector<pair<unsigned int, unsigned int> > vec1 and the contents are
{<0x00000000, 0x000000FF>, <0x10000000, 0x2FFFFFFF>}
what I want is to create another vector, vector<int> vec2, which store
all the first 8 bit heads of the integer in vec1, for the above example,
0x00000000 & 0xFF000000 ==> 0x00000000,

Hi all. Just working on a small virtual machine, and thought about using
vector iterators instead of pointer arithmetic. Question is, why does an
iterator plus any number out of range not generate a out_of_range exception?
Maybe this is a gcc issue?
I'm using gcc version 3.3.3 (cygwin special).
Here's the full sample code:
#include <iostream>

Hi all
I want to create a std::vector that goes from 1 to n instead of 0 to n-1.
The only change this will have is in loops and when the vector returns
positions of elements etc. I am calling this uovec at the moment (for
Unit-Offset VECtor). I want the class to respond correctly to all usage of
STL containers and algorithms so that it is a transparent replacement for
std:vector.
The options seems to be:

I found out that the program

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.
}

Dear All,
For some reason I had got it into my head that std::vector<T>::iterator
and std::basic_string<T>::iterator were certain to be T*. I now see
that this isn't true.
So here's why this matters to me. I have a function that is templated
on an iterator type:
template <typename Iter>

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

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...
