This article presents the basics of Observer Pattern, when to use it and how to implement it in C++.

#include "DummyProduct.h"

int main(int argc, char* argv[])
	DummyProduct product;
	// We have four shops wanting to keep updated price set by product owner
	Shop shop1("Shop 1");
	Shop shop2("Shop 2");


	//Now lets try chaging the products price, this should update the shops automatically
