hey zohaib, this might help u


/*
Language: C\C++
Category: Database\Files
Description:              LIBRARY MANAGEMENT
This is actually a library management software.it uses
files to store
data.it uses files to store data for later use.
-----------------FEATURES----------------------------------
*a student cannot borrow more than 5 books
*student number can contain alphabets(eg.02it65)
*issued book cannot be reissued
*fine is automatically calculated after 15 days.
(each day 50paise per day after the due date)
*book and student deatails can be viewed seperately.
*books which are issued/not issued can be viewed seperately.
*student and book details are stored in *.rrn files.
*there are two .rrn files(student.rrn and book.rrn the
*program uses)
*books and students can be added or removed.
*rrn is my own personal extension
