6) Design the logic for a program that allows a user to enter a number. Display the sum of every number from 1 through the entered number.

9) a. Design an application for the Homestead Furniture Store that gets sales transaction data, including an account number, customer name, and purchase price. Output the account number and name, then output the customer’s payment each month for the next 12 months. Assume that there is no finance charge, that the customer makes no new purchases, and that the customer pays off the balance with equal monthly payments.

    b. Modify the Homestead Furniture Store application so it executes continuously for any number of customers until a sentinel value is supplied for the account number.

10) a. Design an application for Domicile Designs that gets sales transaction data, including an account number, customer name, and purchase price. The store charges 1.25 percent interest on the balance due each month. Output the account number and name, then output the customer’s projected balance each month for the next 12 months. Assume that when the balance reaches $25 or less, the customer can pay off the account. At the beginning of every month, 1.25 percent interest is added to the balance, and then the customer makes a payment equal to 7 percent of the current balance. Assume that the customer makes no new purchases.

     b. Modify the Domicile Designs application so it executes continuously for any number of customers until a sentinel value is supplied for the account number.

 

11) a. Design a program for Huntersville College. The current tuition is $15,000 per year, and tuition is expected to increase by 4 percent each year. Display the tuition each year for the next 10 years.

      b. Modify the Huntersville College program so that the user enters the rate of tuition increase instead of having it fixed at 4 percent.

      c. Modify the Huntersville College program so that the user enters the rate of tuition increase for the first year. The rate then increases by 0.5 percent each subsequent year.

 

15) a. Design a program for the Hollywood Movie Rating Guide, which can be installed in a kiosk in theaters. Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the guide’s featured movie of the week. If a user enters a star value that does not fall in the correct range, reprompt the user continuously until a correct value is entered. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, display the average star rating for the movie.

     b. Modify the movie-rating program so that a user gets three tries to enter a valid rating. After three incorrect entries, the program issues an appropriate message and continues with a new user.
