Rectangle Area—Complete the
If you have downloaded the book’s source code from www.pearsonhighered.com/gaddis, you will find a partially written program named AreaRectangle.java in this chapter’s source code folder. Your job is to complete the program. When it is complete, the program will ask the user to enter the width and length of a rectangle, and then display the rectangle’s area. The program calls the following methods, which have not been written:
- getLength—This method should ask the user to enter the rectangle’s length, and then return that value as a double.
- getWidth—This method should ask the user to enter the rectangle’s width, and then return that value as a double.
- getArea—This method should accept the rectangle’s length and width as arguments, and return the rectangle’s area. The area is calculated by multiplying the length by the width.
- • displayData—This method should accept the rectangle’s length, width, and area as arguments, and display them in an appropriate message on the screen.

- Please provide answer in C#: Slot Machine Simulation A slot machine is a gambling device into which the user inserts money and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money that the slot machine dispenses back to the user. Create an application that simulates a slot machine. Figure 8-23 (on page 539 of your book) shows an example of how the form should look. The application should let the user enter into a TextBox the amount of money he or she is inserting into the machine. When the user clicks the Spin button, the application should display three randomly selected symbols. (Slot machines traditionally display fruit symbols. You will find a set of fruit symbols attached to this dropbox for your use - from the Student Sample Programs provided by the book author.) If none of the randomly displayed images match, the program should inform the user that he or she has won…arrow_forwardRock, Paper, Scissors Game Create a application using (C#) in Microsoft Visual Studio 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 is 2, 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 use 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.…arrow_forwardPYTHON PROGRAMMING 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…arrow_forward

To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. 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. First, you should create a class named RoomDimension that has two fields: one for the length of the room and one for the width. The RoomDimension class should have a method that returns the area of the room. (The area of the room is the room’s length multiplied by the room’s width.) Next you should create a RoomCarpet class that has a RoomDimension object as a field. It should also have a field for the cost of the carpet per square foot. The RoomCarpet class should have a method that returns the total cost of the carpet.

Create a program that simulates a slot machine. When the program runs, it should do the following: Asks the user to enter the amount of money he or she wants to enter into the slot machine. Instead of displaying images, the program will randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries; if the number is 1, the selected word is Oranges; and so forth. The program should randomly select a word from this list three times and display all three of the words. If none of the randomly selected words match, the…arrow_forward
- Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and ay at the end of the word. For example, dog becomes ogday and cat becomes atcay. Write a program named PigLatin that allows the user to enter a word and displays the pig Latin version.arrow_forwardProgram Description: PasswordGenerator.java You have to implement a program that creates three buttons to display the digits of a password a button to generate a password a button to reset the password Additional Requirements: The top three digit buttons are not interactive as they are only used to display numbers from 0 to 9. The text size of the buttons should be 30 pixels and font should be Arial. There should be 5 pixels distance between the buttons.arrow_forwardIn C# language using Microsoft Visual Studio in Windows Forms App (.NET Framework) A slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button).

- Widgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forwardPopulation Tracker Learning Objective: Using Python Repetition and Loop Statements Problem Description Write a Python program (Console and GUI) that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user to enter the following information: starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. For example, assume the user enters the following values: Starting number of organisms: 2 Average daily increase: 30% Number of days to multiply: 10 The program should display the following table of dataarrow_forwardGPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated.
