Question

Create a system which ends when the user wants it to. After a user has used this system, there is an option of another user using it. The system should ask whether you want to continue or not. Below is a sample of the input/output system.

Are you a student or a librarian?
Hit 1 for student and 2 for librarian.
$1
Enter Name: $William
How many books do you want to take?
$4
What books do you want to take?
Enter book ISBN no(Ex: 242424) // Let's assume we have a 6 digit ISBN number for this project. Put any number to test //your system.
$454092

$535212

$676685

$128976
William borrowed 4 books.
Hit 1 to continue 0 to end system
$1
Are you a student or a librarian?
Hit 1 for student and 2 for librarian.
$2
Enter Name: $Miss Benny
0 Lisa borrowed 1 books //format: student_id Student_name "borrowed" number_of_books "books"
1 William borrowed 4 books
Type student id for more info.
$ 0
Lisa borrowed 1 books
235633
Hit 1 to continue 0 to end system
$0

//There needs to be an array for studentid, student name, isbn index start #, isbn index end #, and libarian name

This is also C++,

If you need further information please specify in the comments and I will edit the problem as needed. I need this information ASAP please.

The $ represents inputs made by the "user"
