Question

Design an inventory class that stores the following members: serialNum:An integer that holds a part's serial number anufactDate: lotNum A member that holds the date the part was manufactured An integer that holds the pasrt's lot number The class should have appropriate member functions for storing data into, and retrieving data from, these members Next design a stack class that can hold objects of the class described above Last, design a program that uses the stack class described above. The program should have a loop that asks the user if he or she wishes to add a part to inventory, or take a part from inventory. The loop should repeat until the user finishes. If the user wishes to add a part to inventory, the program should ask for the serial number, date of manufacture, and lot number. The data should be störed in an object, and pushed onto the stack. If the user wishes to take a part from inventory, the program should pop the top-most part from the stack and display the contents of its member variables When the user finishes the program, it should display the contents of the member values of all objects that remain on stack
