Create a VB application that lets the user enter his or her weight (in pounds) and height (in inches). If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. The application should calculate the user’s body mass index (BMI). The BMI is often used to determine whether a person is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:
BMI = weight × 703/height2

- Account numbers sometimes contain a check digit that is the result of a mathematical calculation. The inclusion of the digit in an account number helps ascertain whether the number is a valid one. Write an application named CheckDigit that asks a user to enter a four-digit account number and determines whether it is a valid number. The number is valid if the fourth digit is the remainder when the number represented by the first three digits of the four-digit number is divided by 7. For example, 7770 is valid, because 0 is the remainder when 777 is divided by 7. The next problems rely on the generation of a random number. You can create a random number that is at least mi n but less than max using the following statements: Random ranNumberCenerator = new Random(); int randomNumber; randomNumber = ranNumberGenerator .Next(min, max);arrow_forwardCreate a lottery game application named Lottery. Generate three random numbers, each between 1 and 4. Allow the user to guess three numbers. Compare each of the users guesses to the three random numbers, and display a message that includes the users guess, the randomly determined three-digit number, and the amount of money the user has won as follows: Â Make certain that your application accommodates repeating digits. For example, if a user guesses 1, 2, and 3, and the randomly generated digits are 1, 1, and 1, do not give the user credit for three correct guesses-just one.arrow_forwardIn Chapter 2, you created a program for Marshalls Murals that prompts a user for the number of interior and exterior murals scheduled to be painted during the next month. The program computes the expected revenue for each type of mural when interior murals cost $500 each and exterior murals cost $750 each. The application should display, by mural type, the number of murals ordered, the cost for each type, and a subtotal. The application also displays the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones. Now create an interactive GUI program named MarshallsRevenueGUI that performs all the same tasks.arrow_forward
- The Donut Shoppe sells four varieties of doughnuts: Glazed (1.05), Sugar (1.05), Chocolate (1.25), and Filled (1.50). It also sells regular coffee (1.50) and cappuccino (2.75). The store manager wants you to create an application that displays a customers subtotal, 6% sales tax, and total due. Create a Windows Forms application. Use the following names for the project and solution, respectively: Donut Project and Donut Solution. Save the application in the VB2017\Chap06 folder. Create the interface shown in Figure 6-57. When coding the application, use one independent Sub procedure to determine the subtotal, which is the total cost without the sales tax. Use a function to determine the sales tax. Use an event-handling Sub procedure to clear the output. Save the solution and then start and test the application.arrow_forwardFor each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program for The Carefree Resort named ResortPrices that prompts the user to enter the number of days for a resort stay. Then display the price per night and the total price. Nightly rates are $200 for one or two nights; $180 for three or four nights; $160 for five, six, or seven nights; and $145 for eight nights or more.arrow_forwardDanielle, Edward, and Francis are three salespeople at Holiday Homes. Write an application named HomeSales that prompts the user for a salesperson initial (D, E, or F). Either uppercase or lowercase initials are valid. While the user does not type Z, continue by prompting for the amount of a sale. Issue an error message for any invalid initials entered. Keep a running total of the amounts sold by each salesperson. After the user types Z or z for an initial, display each salespersons total, a grand total for all sales, and the name of the salesperson with the highest total.arrow_forward
- When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period:d =1/2 gt2The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time in seconds that the object has been falling. Create an application that allows the user to enter the amount of time that an object has fallen and then displays the distance that the object fell. The application should have a method named FallingDistance. The FallingDistance method should accept an object’s falling time (in seconds) as an argument. The method should return the distance in meters that the object has fallen during that time interval.arrow_forwardA Costume shop requests a Computer application that advertizes Costume rentals.
