This assessment item relates to the unit learning outcomes as in the unit descriptors. This assessment covers the following LOs.
LO1 Demonstrate understanding of classes, constructors, objects, data types and instantiation; Convert data types using wrapper methods and objects
LO2 Independently analyse customer requirements and design object-oriented programs using scope, inheritance, and other design techniques; Create classes and objects that access variables and modifier keywords. Develop methods using parameters and return values
LO3 Demonstrate adaptability in building control and loop structures in an object-oriented environment; Demonstrate use of user defined data structures and array manipulation
Project: Comparing Discounts
Problem Description:
Suppose that you got a developer role in the taxation office, your first task is to develop demonstrate a program to store manager in relation to calculate the tax to be paid by the employee for each bracket rate starting from 10% to 20%, with an increment of 1/2. Assume you have been hired as a developer in the taxation office. Your first task will be to create and demonstrate to the store manager a program that will calculate the tax to be paid by the employee for each bracket rate ranging from 10% to 20%, with a 1/2 increment.
Create a program that allows billing staff to enter their annual income (I) and see the tax amount (TA) for each bracket rate (B). Here’s an example:
Write a program that lets the billing staff enter the yearly income (I) and display the tax amount (TA) for each bracket rate (B). Here is a sample run:
Output
Income: 100000
Bracket Rate ___________ Tax Amount
10% $10000
10.5% $10500
11% $11000

9.5 %
$19500
20% $20000

End output
Use the formulas below to compute tax rate (DA).
TA = I * B
Design: (Describe the major steps for solving the problem.)
Coding: (Copy and Paste Source Code here. Format your code using Courier 10pts)
Output screenshot: (Paste your output screenshot here)
Testing: (Describe how you test this program)
Submit the following items:
1. Submit this Word document with solution via LMS (you must submit the program)
Hint:
1. Can you get the first four rows manually? This will help you understand how to compute the numbers mathematically.
2. Can you write a program to produce the first four rows? This will help you see the pattern.
3. Can you generalize it in a loop to produce all the rows?
4. Finally, format the output correctly.
