11. Write a program to perform the following operations on Rational numbers (using Structures & pointers):
    
    1. Read a Rational number
    2. Addition of two Rational numbers
    3. Subtraction of two Rational numbers

12. A Bookshop maintains the inventory of books that are being sold at the shop. The list includes details such as author, title, price, publisher and stock position. Whenever a customer wants a book the sales person inputs the title and the author and the system searches the list and displays whether it is available or not. If it is not an appropriate message is displayed, if it is then the system displays the book details and request for the number of copies are required, if the requested copies are available the total cost of the requested copies is displayed otherwise the message "required copies not in stock" is displayed. Write a program for the above in structures with suitable functions.
13. Create a student data file (roll no., name, date of birth, rank) and code a program with options (use pointers & structures)
    
    1. Listing names, dob sorted on names
    2. Listing names, dob sorted on dob
    3. Listing names, dob sorted on names, dob
14. 1. Write a C program To copy the one file contents to the another file (using commandline arguments)
    2. Write a C Program to count the frequencies of words in a given file.
