Description
- Below is the required part of the Genre The name of the class must be Genre. The interface for the class must be written in a file called Simple Genre .h and its implementation must be written in a file called SimpleGenre.cpp.
▪ The Genre class keeps the name of the genre as the only data member. Make sure to implement the get function for this data member since we will use them to test your program.
▪ Implement the default constructor, which initializes the GenreName data member. Implement the getter and setter function for this data member. Additionally, implement your own destructor and copy constructor, and overload the assignment operator. Although you may use the default ones for some of these special functions, you are advised to implement them (some may have no statements) so that it will be easier for you to extend them for Part B.
- Do not delete or modify any part of the Given data members or member You are not allowed to define additional functions and data members to this class for Part A.

- Below is the required part of the Book Collection class that you must write in Part A of this The name of the class must be Book Collection. The interface for the class must be written in a file called Simple Book Collection. and its implementation must be written in a file called Simple Book Collection. cpp. Do not delete or modify any part of the given data members or member functions. You are not allowed to define additional functions and data members to this class for Part A.
| #ifndef __SIMPLE_BOOKCOLLECTION_H
#define __SIMPLE_BOOKCOLLECTION_H #include <string> using namespace std; #include “SimpleGenre.h” class BookCollection{ public: BookCollection(); ~BookCollection(); BookCollection(const BookCollection& bcToCopy); void operator=(const BookCollection& right); void displayGenres() const; bool addGenre(const string genreName); bool removeGenre(const string genreName); string getName() const; void setName(const string bcName); private: struct GenreNode { Genre g; GenreNode* next; string name; int genreCount; GenreNode* head; GenreNode* findGenre(string genreName); #endif |
You must keep the genres in a linked-list of Genre Nodes whose head pointer is Genre Node *head. In this class definition, you also see the prototype of a private function called find Genre. You may want to implement such an auxiliary function and use it in your add and remove functions (then in some other functions for Part B). This function takes the name of a genre, searches it in the linked list of genres, and returns a pointer to the Genre Node that contains that genre if the genre exists in the system. Otherwise, it returns NULL. This auxiliary function may help you write more clear codes. However, if you do not want to use it, just define an empty function (with no statements) in your SimpleBookCollection.cpp file.
Things to do:
▪ Implement the default constructor, which creates an empty book collection system. Also overload the assignment operator and implement the destructor and copy constructors.
▪ Implement the getter/setter functions for the name data member.
▪ Implement the and remove genre functions whose details are given below:
Add a genre: This function adds a genre to the system. The name of the genre is specified as a parameter. In this system, genre names are unique. Thus, if the user attempts to add a genre with an already existing name, then display a warning message, do not add the genre and return false.
Otherwise, if the genre does not exist in the system, add the genre to the system and return true. Note that names are case insensitive (i.e., Fantasy and FANTASY are the same thing).
Remove a genre: This function removes a genre from the system. The name of this genre is specified as a parameter. If the genre with the given name exists in the system, remove it from the system and return true. Otherwise, if there is no genre with the given name, do not perform any action and return false. Display a warning message.
Display all genres: This function should display the names of all genres in the system one per line. If the there are no genres in the system, display –EMPTY–.
Genre name1
Genre name2 · · ·
3. To test Part A, write your own main function in a separate file. Do not forget to test your code for different cases such that the system is created and the above-mentioned functions are employed. However, do not submit this file. If any of your submitted files contains the main function, you may lose points.
| #ifndef __AUTHOR_H
#define __AUTHOR_H #include <string> using namespace std; class Author{ public: Author(); Author(const int id, const string name); int getID() const; void setID(const int id); string getName() const; void setName(const string id); private: string name; int id; }; #endif |
| #ifndef __BOOK_H
#define __BOOK_H nclude <string> using namespace std; #include “Author.h class Book{ public: Book(); Book(const string name); ~ Book(); Book(const Book& book To Copy); void operator=(const Book& right); string getName() const; void set Name(const string book Name); bool add Author(const int id, const string name); bool remove Author (const int id); void display Authors() const; private: stuct Author Node { Author a; Author Node* next; AuthorNode* head; string name; Author Node* find Author(int id); }; #endif |
Here is some information about the functions to be implemented in the Book class:
Add an author: This function adds an author to the book. The id and name of the author are specified as parameters. In this system, author ids are unique. Thus, if the user attempts to enter an author that exists for that book, display a warning message and do not perform the requested action.
Remove an author: This function removes an author from the book. The id of the author is specified as a parameter. If there is no author with the given id, display a warning message and do not perform the requested action.
Display authors: This function lists all authors added to the book. The output should be in the following format. If the there are no authors of the book, display –EMPTY–.
Author ID1, Author name1
Author ID2, Author name2
Then, extend the Genre class from Part A, such that now it keeps the books of a single genre. These books must be kept in another LINKED-LIST. Note that the number of books in a genre is not known in advance. Here, do not forget to implement the constructor, destructor, and copy constructor of this Genre class. Also do not forget to overload its assignment operator. Otherwise, you may encounter some unexpected run-time errors. This time, the interface of the Genre class must be written in a file called Genre.h, and its implementation must be written in a file called Genre.cpp.
After extending the Genre class, now work on the implementation of the following functionalities that your Book Collection system should support:
- Add a genre
- Remove a genre
- Display all genre
- Add a book to a genre
- Remove a book from a genre
- Add an author to a book in a genre
- Remove an author from a book in a genre
- Show detailed information about a particular genre
- Find the genre (s) and book(s) associated with a specific author i
Add a genre: This function adds a genre to the system. The name of the genre is specified as a parameter. In this function, the book list is not specified; the book(s) (and their author(s)) will be added later. In this system, genre names are unique (case insensitive). Thus, if the user attempts to enter a genre with an already registered name, display a warning message and do not perform the requested action. This function is very similar to what you implemented in Part A. But now, for Part B, you will need to create an empty book list for the genre when you add it to the system.
remove a genre : This function removes a genre from the system. The name of this genre is specified as a parameter. If there is no genre with the given name, display a warning message and do not perform the requested action. Note that this function also clears the book list of the specified genre as well as author lists for the books. This function is very similar to what you will implement in Part A. But now, for Part B, you will need to remove its book list along with the author lists of the books when you remove the genre from the system.
Display all genres: This function lists all genres already registered in the system. The output should be in the following format. If the there are no genres in the system, display –EMPTY–.
Genre name1
Genre name2
·Add a book to the genre:
This function adds a book to the book list of a genre. The genre name for which the book is submitted to and the name of the book are specified as parameters. Note that the author list is initially empty and authors will be added later. In this function, you should take care of the following issues:
- If the genre with the specified name does not exist in the system, display a warning message and do not perform the requested
- All book names are unique (case insensitive) within the same Thus, if the user attempts to add a book with an existing name in the same genre, display a warning message and do not perform the requested action. However, different genres can have books with the same name. Note that a book can be entered to multiple genres.
Remove a book from the genre: This function removes a book from the book list of a genre. Note that this operation should also clear the author list of the book. The genre name for which the book is submitted to and the name of the book are given as parameters. If there is no genre withthe specified name or if the specified book name is not in the book list of the specified genre, display a warning message and do not perform the requested action.
Add an author to a book in a genre: This function adds an author to a book in a given genre. The genre name for which the book will be entered to, and the name of the book are specified as parameters along with the author name and author id. In this function, you should take care of the following issues:
- If the genre with the specified name does not exist in the system or the given book does not exist in that genre, display a warning message and do not perform the requested
- All author ids are Thus, if the user attempts to add an author with an existing id in the same author list, display a warning message and do not perform the requested action. However, different books can have authors with the same id.
Remove an author from a book in a genre: This function removes an author fromthe author list of the given book in the given genre. The id of the author, the genre name to which the book is entered and the name of the book are given as parameters. If there is no genre with the specified name or if the specified book name is not in the book list of the specified genre or if the author id is not in the author list of the corresponding book, display a warning message and do not perform the requested action.
Show detailed information about a particular genre: This function displays all of the information about a genre whose name is specified as a parameter. The output should be in the following format. If the genre with the specified name does not exist in the system, display –EMPTY– after the first line. Authors of a book will be listed following the book name and will start after a tab.
Genre name
Book name1
Author ID1, Author name1
Author ID2, Author name2
Book name2
Author ID3, Author name3
Author ID4, Author name4
Author ID5, Author name5
Find the genre(s) and book(s) associated with a specific author: This function lists all the genres whose book lists contain the specified a book which is authored by the given author ID. Multiple genres can have multiple books, which can have the same author id. The output should b the following format. If the specified author does not participate in any book, display –EMPTY– after the author ID and name. Found book names follow the genre name and start after a tab.
uthor ID, Author name
Genre name (for the 1st genre)
Book name (for the 1st book in 1st genre)
Book name (for the 2nd book in 1st genre)
Genre name (for the 2nd genre)
Book name (for the 1st book in 2nd genre)
Book name (for the 2nd book in 2nd genre)
Book name (for the 3rd book in 2nd genre)
Below is the required public part of the BookCollection class that you must write in Part B of this assignment. The name of the class must be BookCollection. The interface for the class must be written in a file called BookCollection.h and its implementation must be written in a file called BookCollection.cpp. Your class definition should contain the following member functions and the specified data members. However, this time, if necessary, you may also define additional public and private member functions and data members in your class. You can also define additional classes in your solution. However, you are not allowed to delete any of the given functions or modify the prototype of any of these given functions.
