Let us suppose that we have 3 books (see table below), each of which contains a number of chapters and every chapter contains a number of sections. For example the book Data Structure contains 3 chapters (Queues and Stacks, Linked‐Lists, Sorting) and the chapter Queues and Stacks contains 2 sections (Queues, Stacks). Write a C++ program that will use arrays to store the information about books, chapters, and sections. The program will ask the user to enter an index and then will display the name of the book, the name of the chapter and the name of the section. For example, if the user enters 2.2.2 then the program will display:
Book: Operating Systems
Chapter: Scheduling
Section: First Come First Serve

Is there a specific problem or question about that we could help you with?

What's your question?
...assuming you're not just asking for someone to do your homework as that would be a violation of the rules.
