Objectives:

Continue practicing past concepts

Practice building basic $C++$ classes

Practice building $C++$ classes that use inheritance

Assignment:

Build the three classes defined below:

Inventory $($base class$)$

Book $($derived class$)$

Puzzle $($derived class$)$

The UML diagrams for the classes are as follows:

$\backslash$table$[[$Puzzle$],[-$ category; string$],[-$ ageRange: string$],[-$ pieceCount: int$]]$

$\backslash$table$[[$Inventory$],[$# name: string$],[$# itemDescription: string$],[$# itemID: string$],[$# stockNumber: int$],[+$ Inventory$()],[+$ getName$()$: string$],[+$ getltemDescription$()$: string$],[+$ getltemID$()$: string$],[+$ getStockNumber$()$: int$],[+$ setName$($string name$)$: void$],[+$ setltemDescription$($string$],[$itemDescription$)$: void$],[+$ setltemID$($string itemID$)$: void$],[+$ setStockNumber$($int stockNumber$)$: void$]]$

$\backslash$table$[[$Book$],[-$ pageNumber: int$],[-$ author: string$],[-$ genre: string$],[-$ publisher: string$],[+$ Book$0],[+$ Book$($string name, string itemDescription,$],[$string itemiD, int stockNumber, int pageNumber,$],[$string author, string genre, string publisher$)],[+$ getPageNumber$0$: int$],[+$ getAuthor$0$: string$],[+$ getGenre$0$: string$],[+$ getPublisher$0$: string$],[+$ setPageNumber$($int pageNumber$)$: void$],[+$ setAuthor$($string author$)$: void$],[+$ setGenre$($string genre$)$: void$],[+$ setPublisher$($string publisher$)$: void$]]$

For these classes, all getters$/$setters are standard getters$/$setters$.$ They also have constructors with parameters that should set their variables and the variables of Inventory.

Once you've verified your classes work as intended, create a main file to use the classes. Your main function should first establish two vectors: one of Book type, one of Puzzle type. Then, you should take in a file $($you should verify this file exists in a loop$)$ and open it for reading $($inventory$.$txt and store.txt have been provided to you$).$

The file format should have each contact indicated by "book" or "puzzle". Then, you'll read from the file a certain number of times. Each field $($i$.$e$.,$ name, item description, item ID$,$ etc$)$ will be on separate lines. Take a look at the file given to see the order of the fields. This means, NOT including the book$/$puzzle tags, book entries will have $8$ lines and puzzle entries will have $7$ lines. Build the appropriate object based on the tag and add it to the appropriate vector. Loop reading from the file until all items are read.

Once you're done reading from the file, close the file. Then, display all of the items to the user in nicely formatted manner $($example given in execution screenshots!$).$
