Inventor Class
Design an Inventory class that can hold information and calculate data for items in a retail store’s inventory. The class should have the following private member variables:
| Variable Name | Description |
| itemNumber | An int that holds the item’s item number. |
| quantity | An int for holding the quantity of the items on hand. |
| cost | A doubl e for holding the wholesale per-unit cost of the item |
| totalCost | A double for holding the total inventory cost of the item (calculated as quantity times cost). |
The class should have the following public member functions:
| Member Function | Description |
| Default Constructor | Sets all the member variables to 0. |
| Constructor #2 | Accepts an item’s number, cost, and quantity as arguments. The function should copy these values to the appropriate member variables and then call the setTotalCost function. |
| setltemNumber | Accepts an integer argument that is copied to the itemNumber member variable. |
| setQuantity | Accepts an integer argument that is copied to the quantity member variable. |
| setCost | Accepts a double argument that is copied to the cost member variable. |
| setTotalCost | Calculates the total inventory cost for the item (quantity times cost) and stores the result in total Cost. |
| getltemNumber | Returns the value in itemNumber. |
| getQuanti ty | Returns the value in quantity. |
| getCost | Returns the value in cost. |
| getTotalCost | Returns the value in total Cost. |
Demonstrate the class in a driver program.
Input Validation: Do not accept negative values for item number, quantity, or cost.

Circle Class (Easy)
Write a Circle class that has the following member variables:
radius : a double
The class should have the following member functions:
Default Constructor: default constructor that sets radius to 0.0.
Constructor: accepts the radius of the circle as an argument.
setRadius: an mutator function for the radius variable.
getRadius: an accessor function for the radius variable.
getArea: returns the area of the circle, which is calculated as area = pi * radius * radius
getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius
Step1: Create a declaration of the class.
Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating
Circle objects, and then reporting the circle’s area, and circumference.
You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…
Account Class) Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type intto represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. Theconstructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display anerror message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amountdoes not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a messageindicating "Debit amount exceeded account balance." Member function getBalance should return the current balance. Create a programthat creates two Account objects and tests the member functions…

For example, 8 hours would be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. The class should have a constructor that accepts a number of hours, as well as member functions for storing and retrieving the hours and days. The class should also have the following overloaded operators: • (+) Addition operator. When two NumDays objects are added together, the over- loaded + operator should return the sum of the two objects’ hours members. • (-) Subtraction operator. When one NumDays object is subtracted from another, the overloaded − operator should return the difference of the two objects’ hours members. Part 2: Design a class named TimeOff.
