10A- Design a program for Hunterville College. The current tuition is 20,000 per year, and tuition is supposed to increase by 3% each year. Display the tuition each year for the next 10 years.
10B- Modify the Hunterville College program so the user enters the rate of tuition increase instead of having it fixed at 3%.
10C- Modify the Hunterville College program so the user enters the rate of tuition for the first year. The rate then increases by .5% for each subsequent year.
Lab#6 (Exercise #2a, #2b, and , #9, Pages 265-269)
2A- Design the logic for a program that allows a user to enter 20 numbers, then displays each number and its difference from the numeric average of the numbers entered.
2B- Modify the above program so that the user can enter any amount of numbers up to 20 until a sentinel value is entered.
9- Design a program that computes pay for employees. Allow a user to continuously input employees’ names until an appropriate sentinel value is entered. Also input each employees hourly wage and hours worked. Compute each employees gross pay, withholding tax percentage, withholding tax amount, and net pay. Display the results for each employee. After the last employee has been entered, display the sum of all the hours worked, the total gross payroll, the total withholding for all employees, and total net payroll.
Weekly Gross Pay Witholding %
0-300 10
300.01-550 13
550.01-800 16
800.01 and up 20
Lab#7 (Exercise #2, #6a, and , #6b, Pages 317-318)
2- Geraldine’s Landscaping Service and Gerard’s Lawn Maintenance are merging their businesses and want to merge their customer files. Each file contains a customer number, last name, address, and property area in sq ft, and each file is in customer number order. Design the logic for a program that merges the two files into one file containing all customers. Assume there are no identical customer numbers.
6A- The Curl Up and Dye Beauty Salon maintains a master file that contains a record for each of its clients. Fields in the master file include the clients ID number, first name, last name, and total amount spent this year. Every week, a transaction file is produced. It contains the customers ID number, the service received (example manicure), and the price paid. Each file is sorted in ID number order.
Design the logic for a program that matches the master and transaction file records and updates the total paid for each client by adding the current weeks price paid to the cumulative total. Not all clients purchase services each week. The output is updated to the master file and an error report that lists any transaction records for which no master record exists.
6B- Modify the program to output a coupon for free haircut each time a client exceeds 1000$ in services. The coupon, which contains the clients name and appropriate congratulatory message, is output during the execution of the update program when a client surpasses 1000$. Make sure that only one coupon is printed per client, even if the client has purchased multiple services to surpass the 1000$ cutoff value.
