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.

Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents
frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid
ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are
designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the
division will be identical to the last dropped digit. This process is illustrated in the following example:
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 is divided by 7. In this case, 12345
divided by 7 leaves a remainder of 4.
Step 4. Assign the Boolean value of the comparison between the remainder and the digit dropped
from the ticket number.
Step 5. Display the result—true or false—in a message box.

The program needs to be ‘smart’ enough as well. When inappropriate values are entered to the program, for example, a negative age, then the program will ask the operator to enter the value again.
Rock, 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.…

Please write a GUI that implements a game, where the user has to click the buttons in the order of their numbering.
* The 9 buttons are arranged in a grid of 3 by 3. Each one has a different number from 1 to 9.
* If the user selects the correct button, it should turn green and become disabled. The score should beincremented by 1.
* If the user selects the incorrect button, it should turn red and all the buttons should become disabled.
* If the user selects the “Reset” button, all buttons should be white and become enabled, their random numbers should be reassigned and the score set to 0.
Thank you.

A slot machine is a gambling device that the user inserts money into 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, which the slot machine dispenses back to the user. Design a program that simulates a slot machine. When the program runs, it should do the following: Ask the user to enter the amount of money he or she wants to insert into the slot machine.
Create an application that simulates a slot machine.
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.

Three-letter acronyms are common in the business world. For example, in Java you use the IDE (Integrated Development Environment) in the JDK (Java Development Kit) to write programs used by the JVM (Java Virtual Machine) that you might send over a LAN (local area network). Programmers even use the acronym TLA to stand for three-letter acronym. Write a program that allows a user to enter three words, and display the appropriate three-letter acronym in all uppercase letters. If the user enters more than three words, ignore the extra words.

1. Write an application that prompts for and reads the user’s first and last name (separately), then displays a string composed of the first four characters of the user’s last name, followed by the first two letters of the user’s first name, followed by a random number in the range of 10 to 99. Assume that the last name is at least four letters long. Similar algorithms are sometimes used to generate usernames for new computer accounts.
Testing: If the inputs were “Michael” and “Jackson,” the output should look like “JackMi42.” Include several tests with different inputs, including your own name.

Declare a constant named YEAR, and initialize YEAR with the value 2050.
Edit the statement myNewAge = myCurrentAge + (2050 − currentYear) so it uses the constant named YEAR.
Edit the statement cout << "I will be " << myNewAge << " in 2050." << endl; so it uses the constant named YEAR.
Execute the program by clicking the Run button at the bottom of the screen.

Write an application that reads a value representing a number of seconds, then displays the equivalent amount of time as a combination of hours, minutes, and seconds. For example, 9999 seconds is equivalent to 2 hours, 46 minutes, and 39 seconds.
Hint: This requires using the % modulus operator. The trick with multiple units of measure like this is to start with the largest unit (hours) and work down.
Testing: Submit testing exhibits using the following inputs: 0, 1, 60, 3600, 3661, and 9999

Population 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
