	cin >> total_num;
	//allocate the dynamic struct
	Car* car = new Car[total_num];
	
	//read I/O and save it
	for (int i = 0; i < total_num; ++i)
	{
		char ch;
		cout << "Car # "<< i+1 << endl;
		cout << "Please enter the provider : ";
		//getchar() read Enter to exit, used for clearing the Enter input

		cin >> car[i].year;
	}
	
	//traverse the struct
	cout << "Here is your collection : " << endl;
	for (int i = 0; i < total_num; ++i)
	{
		cout << car[i].year << " " <<car[i].provider << endl;
	}

	//release the space
	delete[] car;
	return 0;
