You are to write a class named PC to represent features of personal computers. The data members of the class and default values will be:


Data member	Description	Default value	   
name	name of the computer (string) 	"No Name"	   
speed	processor speed in gigahertz (double)	100.0	   
memory	memory size in megabytes (double)	512.0	   
disk	disk drive size in gigabytes (double)	  80.0	   
price 	price in riyals (double)	0.0	 

The class should include the following:
A default constructor that sets default values for all variables. 
An overloaded constructor with parameters.
One get function for each data member that returns the current value.
One set function that sets new values for all data members.
An overloaded operator -= which decreases a PC object’s price by a given double value.
An overloaded operator >> that reads in the values of the data members.
An overloaded operator << that will display the values of the data members. 

Using the PC class as the base class, you need to derive class Laptop for laptop computers that has additional data members screen and weight, both of type double.  screen will hold the diagonal dimension of the laptop's screen in inches and weight will be the weight of the laptop in pounds. 

The derived class should include the following:
A default constructor that sets default values for all variables. 
An overloaded constructor with parameters.
One get function for each data member that returns the current value.
One set function that sets new values for all data members.
An overloaded operator >> that reads in the values of the data members.
An overloaded operator << that will display the values of the data members. 

Write a driver program that declares a dynamic array of laptops, inputs laptops’ information and finally provides the following two options: 
Display the data of all laptops.
Display the data for laptops with a price that lies within a specific range, thus with this option, you will ask the user to input the range. 

Notes: 
You are not going to use all member functions in the driver program. However, you should test them all (you do not need to submit the test).
You should read the size of the dynamic array and the laptops’ information from a file.
You should use separate files for the interface and implementation so that the implementation can be compiled separately from the application program.
