C#
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.
If the account number is valid, output The account number is valid. If the account number is invalid output Invalid. If the account number is too short or too long output Account number invalid - it must have 4 digits.
It is customary to show the result of a calculation in a(n) _________control in the interface.

The Seri Kuala Lumpur School auditorium contains 20 rows (numbered 1 through 20) with 30 seats each (numbered 1 through 30). Write an application that allows a user to continuously enter a row and seat request until a sentinel value is entered. If the row or seat number is out of range, issue an error message. Otherwise, determine whether the seat has already been reserved. If so, display an error message. If not, then charge the user $7.50 for a ticket and display a running total of the user’s purchase. When the user enters a sentinel, display the number of seats taken and the number of seats available in the auditorium.

- C CODE: create a program that will test the user’s proficiency in solving different types of math problems. The program will be menu-driven. The user will select either addition, subtraction, multiplication, or division problems. The program will then display a problem, prompt the user for an answer, and then check the answer displaying an appropriate message to the user whether their answer was correct or incorrect. The user will be allowed 3 tries at each problem. The program will also keep statistics on how many problems were answered correctly. add functions to allow the user to select problems of varying degrees of difficulty In the next Week, you'll need to add functionality to also keep statistics on the number of correct answers vs. the total number of problems attempted. So now let’s add the code for the remaining functions: We’ll start by inserting code to ask the user if they want to see problems that are easy, medium, or difficult. We’ll do this by prompting them to…arrow_forward99 question 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.arrow_forwardJava Programming Write an application that prompts the user for two integers and then prompts the user to enter an option as follows: 1 to add the two integers, 2 to subtract the second integer from the first, 3 to multiply the integers, and 4 to divide the first integer by the second. Display an error message if the user enters an option other than 1 through 4 or if the user chooses the divide option but enters 0 for the second integer. Otherwise, display the results of the arithmetic. Write your .java file here. Include your flowchart and sample output.(Use a switch statement only).arrow_forward

- C# Question Create a desktop application that allows the user to enter a maximum integer. The application should sum all the even integers from zero up to and including that maximum number if it is even. The sum should be displayed in the form. For example: For a maximum integer of 50 the sum is 650. For a maximum integer of 11 the sum is 30. The program should have a method named SumEvens that receives the maximum integer as an argument and returns the sum of the even numbers. The SumEvens method should use a for loop to calculate the sum of the even numbers.arrow_forwardIn C#, falling through a switch case is most often prevented by using the ________ statement• a. end• b. break • C. case• d. defaultarrow_forward3.

The charge for each additional panel is $300. The normal waiting time for installation is two weeks, but customers can pay an express charge of 5% of the total cost to reduce this time. Create an application that collects the required information from the user and calculates the charges for the installation.The user should input the following information: first name, last name, phone, number of panels, deposit amount, and a check box for the express installation option. When the user clicks a button to view the charges, display a group box containing the following information: base installation charge, cost of installing additional panels, total installation cost, deposit amount, and balance due.Error checking should include the following criteria:• The name and phone fields cannot be blank• The number of panels must be an…arrow_forward
- Using 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.
