Write a program for registering and storing computer devices. There are two types of devices: printers and displays.

Displays have an identification number (std::string), a price (double) and a year of appropriation (int).

Printers have an identification number (std::string), a price (double) and a printing speed (double).

Both devices are a type of device (IS_A relationship), so use a base class named Device. Common attributes should be in the base class.

The main function creates a heterogeneous container (array) for some number of devices, and then prints the devices' attributes. Add a print function to the base class as well as the subclasses. Does the base print function need to be virtual?

1. Device.h, Printer.h, Display.h: class declaration headers
2. DeviceMain.cpp: main program

Add a sortDevices function to DeviceMain.cpp. This function should sort the devices array by the idNumber of the devices. Its signature should be:

void sortDevices(Devices* equipments[], int size)

You can use last week's sorting algorithm but with different types. A sorting algorithm requires a way to compare two elements of the sequence it is sorting. For this, it uses one of the comparison operators (<, >, <= or >=). You need to overload this operator in the Device class. Make sure that you are not comparing pointers.

Add at least 5 new device to the array and sort it before printing each element. Make sure that they are printed in alphabetical order.
