Usage (Client Code): ● In the Main method, a NewsPublisher is created, along with two subscribers: Alice?

nd Bob. The subscribers are subscribed to the publisher. When the publisher sends

out a notification (Notify()), all subscribers are automatically notified and updated

with the latest news.

class Program
{

static void Main()

{
var publisher = new NewsPublisher();
var subscriber1 = new NewsSubscriber("Alice");
var subscriber2 = new NewsSubscriber("Bob");

publisher.Subscribe(subscriber1);

publisher.Subscribe(subscriber2);

publisher.Notify("Breaking News: Observer Pattern in C#!");

}
}

Output:

lice received news: Breaking News: Observer Pattern in C#!

Bob received news: Breaking News: Observer Pattern in C#!
