14. (Data Processing) a. A national medical testing laboratory wants a new computer systemto analyze its test results. The system must be capable of processing each day's results aswell as retrieving and outputting a printed report of all results meeting certain criteria,such as all results for a particular doctor or for hospitals in a certain state. Determinethree or four major program units into which this system could be separated. (Hint: Onepossible program unit is "Prepare Daily Results" to create each day's reports.)b. Suppose someone enters incorrect data for a test result, and the error is discoveredafter the system has entered and stored the data. What program unit is needed to cor-rect this problem? Discuss why such a program unit might or might not be requiredby most systems.c. Assume a program unit exists that allows users to change data that has been enteredand stored incorrectly. Discuss the need for including an "audit trail" that would allowreconstructing the changes later as well as when they were made and who made them.

The, given information is regarding data processing. So, the answer has given below:

C++ programming problem: During the tax season, every Friday, the J&J accounting firm provides assitance to people who prepare their own tax returns. Their charges are as follows: a. If a person has low income (<=25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes. b. For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regularly hourly rate for the time over 20 minutes. Write a program that prompts the user to enter the hourly rate, the total consulting time, and whether the person has low income. The program should output the billing amount. Your program must contain a function that takes as input the hourly rate, the total consulting time, and a value indicating whether the person has low income. The function should return the billing amount. Your…
