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);

- PYTHON 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_forwardThe 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_forwardMagic 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_forward
- Write an application that allows a user to enter any number of student quiz scores, as integers, until the user enters 99. If the score entered is less than 0 or more than 10, display Score must be between 10 and 0 and do not use the score. After all the scores have been entered, display the number of valid scores entered, the highest score, the lowest score, and the arithmetic average.arrow_forwardPYTHON CODE Reza Enterprises sells tickets for buses, tours, and other travel services.

The following formula can be used to determine a moving object’s kinetic energy: KE =1/2mv2 In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.arrow_forward

To get the bonus, the customer is given the opportunity three times to guess a number determined by the application from numbers 1 to 20. For each guess number given by the customer, the application will respond as follows:• If the guessed number is smaller than the lucky number, you will see the words "Bigger Number"• If the guessed number is greater than the lucky number, you will see the words "Smaller Number"• If the guessed number is the same as a lucky number, it will match the words "Congratulations ... you found a LUCKY number"As part of the company's IT team, you serve to create a lucky number guessing game console.A.

- The game of Nim starts with a random number of stones between 15 and 30. Two players alternate turns and on each turn may take either 1, 2, or 3 stones from the pile. The player forced to take the last stone loses. Create a nim application in python that allows the user to play against the computer. In this version of the game, the application generates the number of stones to begin with, the number of stones the computer takes, and the user goes first. The Nim application code should: prevent the user and the computer from taking an illegal number of stones. For example, neither should be allowed to take three stones when there are only 1 or 2 left. include an is_valid_entry() function to check user input. include a draw_stones() function that generates a random number from 1 to 3 for the number of stones the computer draws. include separate functions to handle the user’s turn and the computer’s turn. My problem is that the code is not outputting like it's supposed to.…arrow_forwardProperty Tax If you own real estate in a particular county, the property tax that you owe each year is calculated as 64 cents per $100 of the property’s value.
