辅导Patron? class和Book? class 程序、辅导C语言图书馆 Library程序解析Java程序|调试Matlab程序

Task 1
This task will have you create a simple piece of software that simulates a Library. We will start
by creating a Book? class, and a Patron? class. Once we have built those classes we can then
use them as building blocks to implement our rudimentary library. For each task, make sure
that you test your code to make sure it works before moving on to the next one.
Task 1.1
Implement a Book? class. The book class should have the following have private ?member variables
for the ISBN (store as a string), title, author and whether or not the book is checked out or not.
● Write a constructor? that assigns values to each member variable as well as a default
constructor? that leaves data uninitialized.
● Write public? methods for retrieving these data values.
● Write a public ?method for checking a book in and out.
● Write a public ?method -- istream& read_book(istream& is);
○ We will use this function to load a single book’s data into a Book? object.
○ This method will read a Book?’s data in the following form
( Title: "Blah Blah" ) ( ISBN: ###-########## ) ( Author: Jane Doe )
Task 1.2
Add operators for the Book? class. Have the ==? operator check whether the ISBN numbers are the
same for two books. Have !=? also compare the ISBN numbers. Have <and ISBN on separate lines. ==,? !=? should be class methods, and <Task 1.3
Create a Patron? class for the library. The class will contain a user’s name and library card number
as private? member variables.
● Write a constructor? that assigns values to each member variable as well as a default
constructor? that leaves data uninitialized.
● Write public? methods that access this data.
● Write a public ?method -- istream& read_patron(istream& is);
○ We will use this function to load a single patron’s data into a Patron? object.
○ This method will read a Patron?’s data in the following form
( Name: John Smith ) ( Number: #### )
Task 1.4
Create a Transaction ?struct that contains a Book? and a Patron? as member variables.CSCI 1300

Assignment 6
Task 1.5
Create a Library? class. It should contain vectors of Book?s, Patron?s, and Transaction?s.
● Write a constructor that takes two filenames as arguments
○ The first filename will refer to a file containing a list of books (one per line)
○ The second will refer to a file containing a list of patrons (one per line)
○ The file formats will be the same as described in Tasks 1.1 and 1.3
○ You should read each file and populate the Book? and Patron? vectors
● Write methods that add Book?s and Patron?s to the library system.
● Write a method to let a Patron ?check out a Book
○ Use a Library card number and ISBN as inputs
○ If the number isn’t in our list of Patrons?, then print out an error message and exit
the function
○ If the book is already checked out, then print out an error message and exit the
function
○ Otherwise, add a Transaction? to the system.
● Write a method to check in a Book
○ If the Book? wasn’t check out to begin with, print out an error message and exit
the function.
○ Otherwise, set the Book?’s status to be checked in.
○ Don’t worry about creating a Transaction? for this.
● Write a method to print out each Transaction
○ I will leave the formatting up to you.
○ Just make sure you print out the relevant details for the Book/Patron
Task 1.6
Let’s test out the final product in our main.
● Create a Library ?object constructed with booklist.txt? and patronlist.txt
● Create a rudimentary menu using a while? loop and a switch-case? statement.
○ The menu should have the following options
1. Add a book
2. Add a patron
3. Check out a book
4. Check in a book
5. Print out all Transactions
6. Quit Program
○ For choices 1 through 4. Prompt the user for relevant input.CSCI 1300

Assignment 6
Task 2 (Extra Credit -- 10pts)
Write a class called Vector? that will inherit from std::vector?.
● Override the [] operator to check if the index is out of bounds or not
● If the index is out of bounds, throw? a out_of_range? exception.
● Demonstrate our added functionality in your main? with a try-catch? statement
