Need help C programming, im stuck

Question

/*Function Name: check_out_book

Parameters: A book

Purpose: Function checks out a book. Nothing is return

void check_out_book (BOOK_STRUCT* book)

{

}

Answer 1

Without a look at the BOOK_STRUCT declaration we can't help you.  Presumably there are variables which include an int or bool available which should be set to 0 or False when it's checked out and date due which is set when it's checked out.  However, we don't even know what format the Date Due should be to set it.  Without that information we can't tell you how to check it out.

Answer 2

WTF is this?
