Specifications
- The file named wizard_all_items.txt is attached and contains a list of all possible items that a wizard can carry. When the user selects the walk command, read these items from the file, randomly pick one, and give the user the option to grab it.
- User should be able to add items to wizard_all_items to have in inventory
- User should be able to search text file wizard_all_items for items
- The current items that the wizard is carrying should be stored in wizard_inventory.txt. Make sure it updates this file every time the user grabs or drops an item.
- The program should use a function to read the list of items and the wizard’s inventory from a file. If this function can’t find the file, it should throw an exception. Then, the calling code should catch and handle this exception in an appropriate way.
- If the items file is missing, display an appropriate error message and exit the program. Comments are provided on lines 46,48,51 and 53 to indicate where the exceptions should be handled.
- If the inventory file is missing, display an appropriate error message and continue with an empty inventory for the user. That way, the program will create a new inventory file when the user adds items to the inventory.
