Imagine you are developing a network library for a high$-$performance networking application. This library needs to manage connections to remote servers, ensuring that all network resources are properly released and connections are cleanly terminated when they are no longer needed.

A NetworkConnection has already been defined, containing a private method named disconnect that accepts a single string parameter called disconnectionMessage used to provide information about the cause of the disconnection.

Given the following header file:

#include

using namespace std;

class NetworkConnection

$\{$

private:

void disconnect$($string$)$;

public:

~NetworkConnection$()$;

$\}$;

Define a destructor for the NetworkConnection class. The destructor should print a message to sdout saying "Disconnecting from the network...", before calling the disconnect method, with the string literal "shutdown" as a parameter, to log that the connection was terminated due to the program finishing its execution naturally.

Note: Use the NetworkConnection:: notation in your code.
