You have been contracted by a bookstore to create an application that will load a list of books received in a shipment and produce a report about the shipment.

Write a program $($client$)$ that uses the class by creating a BooksReceived object and prompting the user for a file name. $($The file is of the type $.$txt$)$ Appropriate error checking is required to ensure the file exists and can be opened successfully. Also, the name of the file may contain a space; therefore, be sure to use getline$()$ instead of cin when you prompt the user to enter the name of the file. Note: File Name means the path and name of the file.

Class:

Name: BooksReceived

Purpose: To accept and store the data for a list of books that were in a shipment and to provide functions that will manipulate the data.

Constructor:

$$ Zero$-$argument constructor that initializes the data members to $0$ or $$ as appropriate.

$$ Four$-$argument constructor that receives the name of the book store, the date shipped, the number of hardbound books, and the number of paperback books.

Data Members:

$$ nameBookstore $$ string

Cannot be blank.

$$ dateShipped $$ string

Cannot be blank.

$$ numberHardbound $$ int

Must be $1$ or greater.

$$ numberPaperback $$ int

Must be $1$ or greater.

$$ books $$ vector

Functions:

$$ addBook$($string$)-$ void

Accepts a book value as a string and adds it to the vector.

$$ sortBookList$()-$ void

Sorts the vector that contains the list of books received.

$$ countBooksReceived$()$ int

Determines the number of books in the vector and returns this.

Do not use a counter of books added.

$$ calcHardboundPercentage$()$ void

Calculates the percentage of the hardbound books in the shipment.

$$ calcPaperbackPercentage$()$ void

Calculates the percentage of the paperback books in the shipment.

$$ displayBooksReceivedInfo$()$ void

Outputs the shipment information in a formatted manor

FYI: While it is not normally a good process to do user output from inside a Class, this is the shorted and simplest method for the time available for this Lab.

$$ setNameBookstore$()-$ void

Accepts a string containing the book store name value and updates the nameBookstore data member.

$$ getNameBookstore $()-$ string

Returns the value stored in the nameBookstore data member.

$$ setDateShipped$()-$ void

Accepts a string containing the date shipped value and updates the dateShipped data member.

$$ getDateShipped$()-$ string

Returns the value stored in the dateShipped data member.

$$ setNumberHardbound$()-$ void

Accepts an int value containing the number of hardboard books in the shipment and updates the numberHardbound data member.

$$ getNumberHardbound $()-$ int

Returns the value stored in the numberHardbound data member.

$$ setNumberPaperback$()-$ void

Accepts an int value containing the number of paperback books in the shipment and updates the numberPaperback data member.

$$ getNumberPaperback $()-$ int

Returns the value stored in the numberPaperback data member.

Note: Setters and Getters are required even if they are not used.

Formulas:

$$ Need: Calculate the percentage of hardbound and paperback books against the total number of books in the shipment.

o For the percentage, always display only $1$ digit after the decimal point. Some percentages will not have anything after the decimal point. E$.$G$.,20\%,27\mathrm{.}3\%$

o FYI: Some of the percentage values will have no decimal point, and others will have several digits after the decimal point. The information below will help you correctly display $0$ or $1$ digit after the decimal point.

o The formula for calculating the percentage is:

Number of Hardbound books $/$ Total Number of Books $*100$

Below is a code example for both the calculation and the display.

double x $=(3*1\mathrm{.}0)/(11*1\mathrm{.}0)$

$3$ is the number of books $($hardbound or paperback$)$

$11$ is the total number of books in the shipment

Multiplying the integer $3$ or $11$ by $1\mathrm{.}0$ converts it to a double.

cout $<<$ "Hardbound: $"<<$ setprecision$(3)<<(0\mathrm{.}2727*100\mathrm{.}0)<<"\%"<<$ endl;

Multiplying the $0\mathrm{.}2727,$ which is the calculated percentage, by $100\mathrm{.}0$ transforms it into $27\mathrm{.}27.$

The setprecision$(3)$ function above tells the compiler that the data value of $27\mathrm{.}27$ is to be displayed with $3$ digits. This causes the final digit to be rounded up or down, and the output is $27\mathrm{.}3.$

Non$-$Class Functions:

$$ displayBooksReceivedInfo$()$ void

Creates and displays the formatted output of the book shipment information.

Business Rules:

$$ No blank lines allowed in the text file.

$$ The value for the number of hardbound and paperback books in the shipment must be numeric.

$$ The data elements in the text file must be in the exact order given in the instructions in below.

o Bookstore name

o Date of shipment

o Number of hardbound books in the shipment

o Number of paperback books in the shipment

o A list of book titles in the shipment.

$$ Must be at least three titles in the list.

$$ The list of book titles must not be in alphabetic order.

$$ Book titles must not exceed $35$ characters in length.
