This assignment utilizes a class in an application that might be useful in the $$real world.$$ It

requires sorting and computation with data stored in a vector inside a class. In this assignment,

you will design an Object$-$Oriented program and manipulate data using a vector within the class.

REMINDER

Do not put each class code into a single file.

Review the checklist at the end of the instructions before submitting the assignment.

INSTRUCTIONS

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.

Note: The number of hardbound and paperback books does not have match the number in

the text file.

$$ numberPaperback $$ int

Must be $1$ or greater.

$$ books $$ vector$<$string$>$

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$()$ double

Calculates the percentage of the hardbound books in the shipment.

$$ calcPaperbackPercentage$()$ double

Calculates the percentage of the paperback books in the shipment.

$$ 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.

$$ displayBooksReceivedInfo$()$ void

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

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

$27\mathrm{.}3.$

Business Rules:

$$ No blank lines are allowed in the text file.

$$ The value for the number of hardbound and paperback books in the shipment mus
