Carpet Calculator
The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carper. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet, to cover that floor with carpet that costs $8 per square foot would cost $960. (12 × 10 × 8 = 960.) First, you should create a class named RoomDimens ion that has two FeetInches objects as attributes: one for the length of the room, and one for the width. (You should use the version of the FeetInches class you created in
Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet.
Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.

- PYTHON CODE Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and continue to loop your program asking…arrow_forwardTheater Ticket System: A small ten-seat theater has contracted you to build software which will reserve tickets. The theater has two rows of five seats each. Each row is referred to by number (1 or 2) and each seat in the row is referred to by letter (A, B, C, D, and E). When started, the program should ask the user for the row they prefer (row selection). If that row has no empty seats then the program should ask the user if they prefer the other row, if no then display a message stating the next show is tomorrow. Upon selecting a row, the program should present the user with a choice of available seats in the row. The user can then either choose a seat and print the ticket (in this case a simple message will suffice) or return to row selection. If a ticket is printed the program should return to row selection. The program terminates when all seats are reserved.

- Driver’s License Exam The local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. Here are the correct answers: 1. B 2. D 3. A 4. A 5. C 6. A 7. B 8. A 9. C 10. D 11. B 12. C 13. D 14. A 15. D 16. C 17. C 18. B 19. D 20. A Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly…arrow_forwardUsing C# in Microsoft Visual Studio create an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors…arrow_forwardThe Westfield Carpet Company has asked you to write an application that calculates theprice of carpeting for rectangular rooms. To calculate the price, you multiply the area of thefloor (width times length) by the price per square foot of carpet. For example, the area offloor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpetthat costs $8 per square foot would cost $960. (12 3 10 3 8 5 960.)First, you should create a class named RoomDimension that has two fields: one for the lengthof the room and one for the width. The RoomDimension class should have a method thatreturns the area of the room. (The area of the room is the room’s length multiplied by theroom’s width.)Next you should create a RoomCarpet class that has a RoomDimension object as a field. Itshould also have a field for the cost of the carpet per square foot. The RoomCarpet classshould have a method that returns the total cost of the carpet.Figure 8-21 is a UML diagram that shows…arrow_forward
- Kinetic Energy In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy: KE =1/2mv2 In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.arrow_forwardPYTHON programming solotion Develop a program that allows the user to enter a start value of 1 to 4, a stop value of 5 to 12 and a multiplier of 2 to 8. The program must display a multiplication table with results using these values. For example, if the user enters a start value of 3, a stop value of 7 and a multiplier value of 3, the table should be displayed as follows: Multiplication Table 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 additionally Each multiplication problem must be displayed with a problem number. The program must prompt the user to enter an answer to each of the multiplication problems. The correct answer should be displayed after the user enters an answer. A message should be displayed informing the user that the answer entered was correct or incorrect followed by an appropriate motivating comment. A running record of the number of correct and incorrect responses must be kept. After all the problems have been presented the user must be informed of…arrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forward
