Consider the attached example program: an object of type 'A' is inserted
into a 'map<int, Am;'. Why does 'm;' call the copy constructor of
'A' twice in addition to a constructor call?
The constructors and copy constructors in 'A' report when they are
called. 'whoami' is just a unique identifier assigned to every object of
type 'A'. The output of the program is:
constructor 0
constructor 1

Hello, this program might look abit long, but it's pretty simple and
easy to follow. What it does is read from a file, outputs the contents
to screen, and then writes them to a different file. It uses map<and
heavy overloading.
The problem is, the output file differs from input, and for the love of
me I can't figure out why ;p
#include <iostream>
#include <fstream>
#include <sstream>

Same thing g++ complains when using hash_map<>, but is happy with
map<--I understand hahs_map is not standardized, but since the
compiler didn't complain something like 'hash_map<not defined', I
suppose it's supported and should behave well when I used it
correctly. BUT it didn't.
Here is my code snippet:
class MyKey {
public:
virtual void foo() { return; }

Actually I'm quite sure I've missed something trivial here, but I just can't find it.
Seemingly I cannot read from a const map&
I try
#include <iostream>
#include <map>
using namespace std;

Not always. By default, yes, but you can specify other comparators, eg:
std::map<int, int, std::greaterreversedMap;

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,...

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...
