The following diagram illustrates the classes you will implement in this lab and their relationships.

	Author
Private	(-) name Type: string
	(-) Id Type: int
	(-) birthdate Type: int
Public	(+) Parameterized Constructor
	(+) Setters
	(+) Getters
	(+) printDetails : void

Private	(-) title Type: string
	(-) author Type: Author
	(-) issueYear Type: int
	(-) pages Type: int
Public	(+) Parameterized Constructor
	(+) Setters
	(+) Getters
	(+) printDetails : void

NormalBook		EBook
(-) weight Type: int		(-) sizeInByte Type: int
(-) printType Type: string		(-) fileType Type: string
(+) Parameterized Constructor		(+) Parameterized Constructor
(+) Getters		(+) Getters
(+) Setters		(+) Setters

NOTE 1: In all of your code, do not forget to validate all user input and to make all functions that do not modify the class constant.

NOTE 2: Do not put all of your code in one file; separate implementation from the interface.

NOTE 3: Avoid duplication of code! If something is already done in the base class, do not do it again in the derived class.

Implement class Book. Function printDetails should print information about the book in a well-formatted manner.

Implement class NormalBook, which inherits from class Book. Note the following:

The weight data member represents the weight of the book in grams.

The printType data member can be either Hard-Cover or Paperback.

Function printDetails of the base class should be overridden to print the additional information about the weight and print type.
