Your homework is to create a program to simulate a library. For that, you have to create a massive(array?) whose elements are as follows: *see the first few lines of the example code - struct raamat{*

You have to create a program which would simulate the lending and returning of books
Program description:
- Reads RAAMATUD.TXT file for a massive(array?)
- After that you have to create a cycle where:
	- You have to display the database of the library with a choice for the user to sort it how he pleases
	- After that the user has to make a choice whether to lend a book, return it or go into the next repetition (of the cycle)
		- When lending, only show the books that are still in the library ie. not lent
		- When returning, only show returnable books
The result of the program:
- The user can simulate a database of the library, see information about those books; lend and return them
