Answer 1

Write a menu driven program in C++ to perform the following functions on a binary file “BOOK.DAT” containing objects of the following class:  

class Book

{ int BookNo;

char Book_name[20];

public:

// function to enter book details

void enterdetails();

//function to display Book details

void showdetails();

//function to return Book_no

int Rbook_no() {return Book_no;}

//function to return Book_name

int Rbook_name() {return Book_name;}

};

1. Append Records

2. Modify a record for a given book no.

(Use seekg(), tellg() for this purpose)

3. Delete a record with a given book no.

4. Search for a record with a given Book name

5. Display a sorted list of records (sort on Book No.)

6. Display a sorted list of records (Sort on Book Name)

Note: (i) Use dynamic array for sorting of the file.

(ii) Use gotoxy() to display the formatted reports.

(iii) The program should be password protected.
