Question

plz help on c program language ..

Answer 1

The
program will prompt the user to enter username and password.
Enter username: fsenel
Enter password: 123456
After the user enters username and password and your program needs to authenticate the user
by reading “user.txt” file. In this file each line represents a user and the format of a line is as
follows (the tokens are space delimited):
<Firstname> <Lastname> <Username> <Password> <Role>
If there is no user with the username entered, your program should print “No user is found
with username fsenel” message on the screen and terminate the execution immediately.
If the user exists but the username and password do not match, then your program should
print “Username and password do not match” message on the screen and terminate the
execution immediately.
If the username and password match, then your program should print the menu depending on
the user’s role. If the user is admin you should print the admin menu, if the user is student
you should print student menu.
Admin Menu
************************************************************
* Welcome to AIU Library Management Program *
************************************************************
* Select: *
* 1. Search Book *
* 2. Add New Book *
* 3. Add New User *
* 4. Quit *
************************************************************
If the user does not enter a number between 1 and 4 then your program should re-print the
admin menu. If the user enters 1 “Search Book” sub menu will be showed up, if the user
enters 2 the user will be able to add a new book, if the user enters 3 the user will be able to
add a new user, if the user enters 4 your program will be terminated.
Student Menu
************************************************************
* Welcome to AIU Library Management Program *
************************************************************
* Select: *
* 1. Search Book *
* 2. Quit *
************************************************************
If the user does not enter 1 or 2 then your program should re-print the admin menu. If the user
enters 1 “Search Book” sub menu will be showed up, if the user enters 2 your program will
be terminated.
Search Book Sub-Menu
************************************************************
* Search Book *
************************************************************
* Select: *
* 1. Search By Title *
* 2. Search By Author *
* 3. Main Menu *
************************************************************
To search books you should read “books.txt” file. In this file each line represents a book.
Since book names, author names, publisher and edition may contain more than one word they
are identified inside square brackets. Please see user.txt file. The format of each line is as
follows
[<Title>] [<Author name>] [<Publisher>] [<Edition>]
Example:
[C How to Program] [Paul Deitel] [Pearson] [International Edition]
If the user enters 1 your program will print
Enter title of the book: C How to Program
Title: C How to Program
Authors: Paul Deitel
Publisher: Pearson
Edition: International Edition
If the user enters 2 your program will print
Enter author of the book: Paul Deitel
Title: C How to Program
Authors: Paul Deitel
Publisher: Pearson
Edition: International Edition
If there is no such a book in the file then print
No books are found
After printing the search result then print “Search Book Sub Menu again”
If the user enters 3 print Main Menu (either Student Menu or Admin Menu depending on the
role)
Add New Book
When admin selects this option, your program should prompt the following items from the
user:
Enter the title of the book: Computer Networking
Enter Author of the book: James F. Kurose
Enter Publisher: Pearson
Enter Edition: International Edition
Then your program should append the following line to the end of the books.txt file
[Computer Networking] [James F. Kurose] [Pearson] [International Edition]
After appending this line to books.txt, the print “The book titled Computer Networking” has
been successfully added to the database. Then print main menu (admin menu)
Add New User
When admin selects this option, your program should prompt the following items from the
user:
Enter First Name: Ahmet
Enter Last Name: Yildiz
Enter username: ayildiz
Enter password: antalya
Enter role (A for admin, S for Student): S
If the username already exists in the file prompt the message “The username is taken please
choose another username” and prompt for another user name
Enter username: ayildiz2
If the username still exists in the file prompt the message again. If not append the following
to the end of user.txt
Ahmet Yildiz ayildiz2 antalya S
you should define struct for Book and User.
