Create an Inventory class with data members for stock number, quantity, and price, and
overloaded data entry and output operators. The data entry operator function should throw:
» An error message, if the stock number is negative or higher than 999
» The quantity, if it is less than 0
» The price, if it is over $100.00
Then perform the following tasks:
a. Write a main()function that instantiates an array of five Inventory objects, and accepts
data for each. Display an appropriate error message for each exception situation. When an
exception is detected, replace all data fields with zeroes. At the end of the program, display
data fields for all five objects. Save the file as Inventory.cpp.
b. Write a main()function that instantiates an array of five Inventory objects and accepts
data for each. If an exception is thrown because of an invalid stock number, force the user
to reenter the stock number for the Inventory object. If the quantity is invalid, do nothing. If the price is in error, then set the price to 99.99. (Add a setPrice()function to the
Inventory class to accomplish this.) At the end of the program, display data fields for all
five objects. Save the file as Inventory2.cpp.
c. Write a main()function that instantiates an array of five Inventory objects and accepts
data for each. If an exception is thrown because of an invalid stock number, force the stock
number to 999; otherwise, do nothing. (Add any needed functions to the Inventory
class.) At the end of the program, display data fields for all five objects. Save the file as
Inventory3.cpp.
d. Write a main()function that instantiates an array of five Inventory objects and accepts
data for each. If any exception is thrown, stop accepting data. Display as many objects as
were entered correctly. Save the file as Inventory4.cpp.
