We have a class called electronic_device that shows the information of an electronic device with two attributes: serial_number and year_built. The classes phone and laptop are inherited from electronic_device. We have another class called smartphone that inherits from phone class. The code is provided bellow:

a) Write the implementation of the regular constructors (not default ones) of electronic_device and laptop classes:

b) Implement the print() function in phone class such a way that it prints out serial_number, year_built and number of cameras for a phone. (Make sure you use the print() function implemented in the base class (electronic_device) as well).

c) What will be the output of the following program (driver) based on the above classes?

d) Write the code for creating a dynamic object of smart phone class with these initial values: serial_number: "samsung123", year_built: 2020, number of camera:3, number_of_apps: 15. Then explain when you create these object which constructors and in which order they are called.
