- 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_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_forwarda. Write a program named CheckMonth that prompts a user to enter a birth month. If the value entered is greater than 12 or less than 1, display an error message; otherwise, display the valid month with a message such as 3 is a valid month. b. Write a program named CheckM0nth2 that prompts a user to enter a birth month and day. Display an error message if the month is invalid (not I through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between I and 29 for February). If the month and day are valid, display them with a message.arrow_forward
- Write a program named Admission for a colleges admissions office. The user enters a numeric high school grade point average (for example, 3.2) and an admission test score. Display the message Accept if the student meets either of the following requirements: A grade point average of 3.0 or higher, and an admission test score of at least 60 A grade point average of less than 3.0, and an admission test score of at least 80 If the student does not meet either of the qualification criteria, display Reject.arrow_forwardA retail company must file a monthly sales tax report listing the total sales for the month and the amount of state and county sales tax collected. The state sales tax rate is 4 percent and the county sales tax rate is 2 percent. Write a program that asks the user to enter the total sales for the month. The application should calculate and display the following: The amount of county sales tax The amount of state sales tax The total sales tax (county plus state) Step 3: Complete the pseudocode by writing the missing lines. (Reference: Defining and Calling a Module, page 78-81). Also, when writing your modules and making calls, be sure to pass necessary variables as arguments and accept them as reference parameters if they need to be modified in the module. (Reference: Passing Arguments by Value and by Reference, page 97 – 103). Module main () //Declare local variables Declare Real totalSales…arrow_forward#7!.arrow_forward
- Create an application that converts Celsius to Fahrenheit. The formula is F=1.8×C+32 where F is the Fahrenheit temperature and C is the Celsius temperature. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. Use the following test data to determine if the application is calculating properly: Celsius Fahrenheit100 2120 3256 132.8 Use Visual Basicarrow_forwardA retail company must file a monthly sales tax report listing the total sales for the month and the amount of state and county sales tax collected. The state sales tax rate is 4 percent and the county sales tax rate is 2 percent. Write a program that asks the user to enter the total sales for the month. The application should calculate and display the following: The amount of county sales tax The amount of state sales tax The total sales tax (county plus state) Step 2: Given the major task involved in this program, what modules might you consider including? Describe the purpose of each module. (Reference: Defining and Calling a Module, page 78).
