Question

I have the code for question 1 and 2 complete. Just need the code for question 3 and 4. C++ programming language please.

P 00 < co Implement all the methods specified above to complete the Inventory class. In the tester program, Inventory.cpp, include the following operations. 1. Create an instance of Inventory class, stockltem1 using the default constructor. Display the itemNumber, quantity, cost and totalCost of stockltem1 2. Create another instance of Inventory class, stockltem2 using the overloaded constructor, and passing the following for itemNumber, quantity and cost - 124, 12, 84.95. Display the associated data for stockltem2. 3. Use the setter functions (mutators) to change the stockltem2 to 243, 50, 9.50. 4. Check the input validation by setting the itemNumber, quantity and cost to -1 using the setter functions. Observe the output. Submit both Inventory.h and Inventory.cpp files. Include sample output for all test cases. Sample Output /* RUN OUTPUT PRODUCED BY THIS TEST PROGRAM Demonstrating the default constructor... Item number: 0 Quantity : 0 Cost 00 0 - MacBook Pro 000 000 #3 $ * R
