Question
Need code in C++.
For this assignment we will begin working on the "Library Inventory System." It is a piece of software that keeps tracks of books in a library's inventory. Including the ability to check-in/check-out books as well as add and remove books from the system. We will be building on this system throughout the semester.
Your software needs to do the following:
Load the inventory from and save the inventory to a file.
Keep track of the author and title of each book, as well as an ID number for each book.
Be able to check in and out books in the inventory based on the book's ID number.
Be able to add and remove books to/from the inventory based on the book's ID number.
You will have some freedom in how you implement the code, but it must meet those requirements
Quitting should save the inventory to the same file it was loaded from.
Bonus 50XP: cin can't deal with spaces very easily, so it is best to separate words with underscores for the title and author. Learn how to use getline and use that instead!
Bonus 140XP: Keep the array sorted by ID number. Create a binary search function and use that to find books!
