- 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_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_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_forward
- uppose you have a certain amount of money in a savings account that earns compoundmonthly interest, and you want to calculate the amount that you will have after a specificnumber of months. The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthlyinterest rate, and the number of months that the money will be left in the account. Theprogram should pass these values to a function named futureValue that returns thefuture value of the account, after the specified number of months. The program shoulddisplay the account’s future value. i attached the screenshot of the output so the output should look like that. the coding should be in c++arrow_forwardText-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. Modify the application below (week3.py) so that the selection variable is sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. You will need to add an if statement in the choice() function to make the correct selection.arrow_forwardPlease 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_forward
- Magic Dates The date June 10, 1960, is special because when it is written in the following format, the month times the day equals the year: 6/10/60 Create an application that lets the user enter a month (in numeric form), a day, and a two-digit year. The program should then determine whether the month times the day equals the year. If so, it should display a message saying the date is magic. Otherwise, it should display a message saying the date is not magic.arrow_forwardname formatter on c# create an application that lets the user enter the following pieces of data: • the user’s first name • the user’s middle name • the user’s last name • the user’s preferred title (mr., mrs., ms., dr., etc.) assume the user has entered the following data: • first name: kelly • middle name: jane • last name: smith • title: ms. the application should have buttons that display the user’s name formatted in the following ways: ms. kelly jane smith kelly jane smith kelly smith smith, kelly jane, ms. smith, kelly jane smith, kellyarrow_forwardTOPICS: Data and Expressions MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. Write an application that prompts for and reads the numerator and denominator of a fraction as integers, then displays the decimal equivalent of the fraction. Hint: This requires casting from integer to double before dividing. Testing: Submit testing exhibits using the following inputs:0, 1 giving 0.0; 1, 2 giving 0.5; 3, 8 giving 0.375; 2, 3 giving 0.666...; 25, 7 giving 3.57128...arrow_forward
