Chapter 13, Problem 6PC
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.

C# Console Application for Minesweeper
In this milestone, students will create three classes: Cell, Board, and Program.
Create a class that models a game cell. A game cell should have the following properties:
a.Its row and column. These should initially be set to -1.
b.Its visited boolean value. This should initially be set to false.
c.Live boolean value. This should initially be set to false. "Live" set to true will indicate that the cell is a "live bomb" cell.
d.The number of neighbors that are "live." This should initially be set to 0.
The Cell class should have a constructor, as well as getters and setters for all properties.
3.Create a class that models a game board. A game board should have the following properties:
a.Size. The board will be square, where the size includes the dimensions of both the length and width of the board.
b.Grid. The grid will be a 2-dimensional array of the type cell.
c.Difficulty. A percentage of cells that will be set to "live" status.

- True or FalseA base class reference variable can reference an object of any class that is derived from the base class.arrow_forwardCruise Recreational Activities Example Recreational activities include things like aerobics, shuffle board, and swimming. Each activity is identified by an activity code and includes other information such as description. Classes are offered for each activity. A class is uniquely identified by a combination of the activity code and the day/time at which it is held. It is assumed that a specific class will never be offered for the same activity at the same day and time, although it could be offered on a different day and/or time. Other information about a class includes the enrollment limit and the current enrollment count. A class will never include more than one activity. A passenger can sign up for a class as long as there is sufficient room in the class. Passengers are identified by a unique passenger number. Other information stored about passengers includes name, address, and age. Passengers have no limit on the number and type of classes they can sign up for. When they…arrow_forwardC++arrow_forward
- Employee class Write a Python program employee.py that computes the cumulative salary of employees based on the length of their contract and their annual merit rate. Your program must include a class Employee with the following requirements: Class attributes: name: the name of the employee position: the position of the employee start_salary: the starting salary of the employee annual_rate: the annual merit rate on the salary contract_years: the number of years of salary Class method: get_cumulative_salary(): calculates and returns the cumulative salary of an employee based on the number of contract years. Round the cumulative salary to two digits after the decimal point. Example: If start_salary = 100000, annual_rate = 5% and contract_years = 3: Then the cumulative salary should be : 100000 + 105000 + 110250 = 315250 Outside of the class Employee, the program should have two functions: Function name Function description Function input(s) Function output(s) / return…arrow_forwardEvery class must have at least one them: Your answer: O Constructor O Destructor 口 Member function OSet function 口 Get function O Data memberarrow_forwardProblem: Employee and ProductionWorker Classes Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker class, and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen Note: The program should be written in python.

- Dynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100.
