C Programming: Borrow Book Function Implementation

This function allows a student to borrow a book by inputting the book ID and the student ID. It first clears the screen using the 'system()' function. Then it prompts the user to input the student ID and book ID.

It then loops through the 'books' array to find the book with the matching ID and checks if it is available. If the book is available, it changes the book's availability status to 0 (not available).

It then loops through the 'students' array to find the student with the matching ID and loops through their 'borrowed_books' array to find an empty spot to add the book ID.

Finally, it breaks out of all loops and returns to the main menu.
