[problem description]
Please design a program to realize the management of book inventory. Please complete the design according to the given main function and program output. The specific requirements are as follows.
1, Please design a Book Class:
1. Include private members:
unsigned int m_ID;//number string m_Name;//title string m_Introductio//brief introduction string m_Author;//author string m_Date;//date unsigned int m_Page;//the number of pages
2. Design getter and setter functions of all member variables. We have introduced getter and setter in the multi file video course, and students can also learn about them in Baidu.
3. Designing construction and destructors does not require outputting information, but students can output and analyze the creation and deletion of each object by themselves:
Book();// Will m_ The ID is initialized to 0, indicating that this is an unassigned object
virtual ~Book();//No specific work Book(const Book& other);//Copy all member variables
2, Please design a Store class, which is a dynamic array class to realize book management:
1. Include private members:
Book *m_pBook;//Points to the Book array dynamically created by the new operation unsigned int m_Count;//Indicates the number of books in stock
2. Design M_ getter and setter functions of count member variables.
3. Design construction and destructor
1) Store();
Will m_ Set count to 0, m_pBook is set to null pointer; And output "Store default constructor called!"
2)Store(int n);
Will m_ Set count to N; Use new to create an array of size n and make m_pBook points to the array; And output "Store constructor with (int n) called!";
3)virtual ~Store();
Will m_ Set count to 0; Judge if m_pBook is not a null pointer, release m_pBook points to space; And output "Store destructor called!";
4)Store(const Store& other);
Implement the deep copy of the object array and output "Store copy constructor called!";
4. Design warehousing operation
The main function of adding a new book to the library is to add a new book to the library.
The function is declared as: void in (book &b)
Note that a new book has been put into storage, so you need to add a storage space. Tip: you can apply for a new space, copy the original data into the new space, put the new book on the last element of the array, and then release the original space, so as to realize the dynamic adjustment of the size of the array.
5. Design issue operation
The main function of stock out operation is to delete this book in the array according to the specified book name.
The function declaration is: void out(string name)
Note that one storage space needs to be reduced because a book is deleted. Tip: you can apply for a new space, copy the undeleted part into the new space, and then release the original space, so as to realize the dynamic adjustment of array size.
6. Find books by ID
It is required to find the book according to the given ID. if it is found, a Book object is returned, in which the information of the corresponding book is stored; If it cannot be found, it returns a Book object, m of the book object_ An ID of 0 indicates that it is not initialized.
The function is declared as: Book findbyID(int ID)
7. Find books by name
It is required to find the book according to the given book name. If it is found, a Book object is returned, in which the information of the corresponding book is stored; If it cannot be found, it returns a Book object, m of the book object_ An ID of 0 indicates that it is not initialized.
The function is declared as: Book findbyName(string name)
8. Design a function to print the information of all books
The function is declared as: void printList()
[input form]
nothing
[output form]
See sample output
[sample output]
Store default constructor called!
The first book is put into storage
The second book is put into storage
The third book is put into storage
Number of books in stock: 3
Find and issue books: Discrete Mathematics
Discrete mathematics has been successfully delivered
Number of books in stock: 2
Find book ID: 3
Find the book with ID 3, Title: c programming
Find book name: Discrete Mathematics
No book with name discrete mathematics was found
Output information of all stock books
There are totally 2 Books:
ID=1; Name:C + + language programming (4th Edition); Author: Zheng Li; Date:201007;
ID=3; Name:c programming; Author: Tan Haoqiang; Date:201006;
