Use the code below in c++ to use try and catch to handle exceptions in at least the following cases:

prevent price from ever being negative

prevent quantity on hand from being negative

For each case, create an exception class in the InventoryItem class that can be used to signal the exception type. When a NegativePriceException is caught by a client code, your code should generate an error message to that effect and continue. When a NegativeQuantityException is caughtby a client code, the client should generate an error message to that effect and set the QuantityonHand data member to 0.

Submit screenshots of your program execution for each test case and a copy of your code in text file.

*Note: price is not given as a data member in the InventoryItem class (PLEASE ADD PRICE DATA MEMBER)

PLEASE let me know if there is any more information needed! * data.csv in bold - Main.cpp, Data.csv, Inventory.cpp, Book.h were all seperated in different files when I compiled this.
