URGENT C++ QUESTION
An "Inventory" class specification can be defined with the following header: class InventoryItem public: // Constructor InventoryItem (char desc, double c, int u) // Destructor InventoryItem); const char getDescription O const; double getCost) const int getUnits ) const private char description;T7 The item description double cost; int units; /I The item cost Number of units on hand This class models an item sold at a store Question1: Finish the specification with whatever code needed (additional attributes and methods) in a header file, then write an implementation for this class (always in a separate "cpp" file) Question2: Add a static member variable to "InventoryItem" class called number_articles, of type "int". This variable should keep how item articles are sold by the store. Add a static member function called getNumberArticles that return that number Question3: Overload the operator"for class "Inventoryltem". The overloaded operator will allow printing the content of an "Inventoryltem" object following the example format bellow: Inventory Item : description=Mars chocolate bar, unit cost=1.09$, quantity is stock-5 Question4: Write a description/implementation for a new class called CashRegister. This class will be used with the InventoryItem class defined earlier (always separate header and implementation file). The CashRegister class should perform the following Ask the user for the item and quantity being purchased. Get the item's cost from the Inventory object. Add a 30% profit to the cost to get the item's unit price. Multiply the unit price times the quantity being purchased to get the purchase subtotal. Compute a 6% sales tax on the subtotal to get the purchase total. Display the purchase subtotal, tax, and total on the screen. Subtract the quantity being purchased from the number of units on hand variable of the Inventoryltem class object Implement both classes, as well as a main function (in its own separate main.cpp). Main code should simulate creation of a stock of item in a first step (which can be static, i.e. no user input), then the process of buyers purchasing items (which should be dynamic, by asking the user which items to purchase). At the end the main will print how the remaining stock information (total number of articles, list of each item description and units in hand). Input Validation: Do not accept a negative value for the quantity of items being purchased Submit a zip file containing all cpp and header files, as well as project file, according to assignment guidelines.
