The assignment also said to test it. If you did, you should know if it
works or not, right ? It seems okay to me, by the way.

I'm curious, what are you going to do in IT that doesn't involve
programming skills ?

You could do it in SQL, by the way. Put the above figures in a table,
put the salaries in another table, and then you can calculate the result
with a single SELECT statement.

Something like:
SELECT s.salary, t.base + ((s.salary - t.min_range) * t.tax) AS tax
FROM tax_table t, salary_table s
WHERE s.salary >= t.min_range
AND s.salary <= t.max_range

As you can see, picking the right language/tool makes the solution a lot
easier.
(Even though your instructor will probably not accept this, what with it
being a programming course, and SQL only barely qualifying as a programming
language...)

A simple solution based upon a table look up follows. The solution is
written using Ada.
Obvious enhancements to this solution include ensuring the input
salary is not less than
0 and not more than 14999.99.

No. Not if it was due on Friday night. But I will give it a try.

You are working too hard!

· Design a program that solves this problem.

I took that to mean "Design a Program". Not write the code.

· Generate a set of input test values.

Here you make a list of random amounts in the range and some out of the
range (to test handling exceptional values) With the answers. Not generated
by the program. This is test data, to test the program. You would use a
known working method to generate this data.

· Perform a design walkthrough to verify your design.

Here you do a walk-through. Take a subset of your test data incomes, and
item by item follow your design ( flow chart or whatever ) step by step,
solving for the tax amount. Compare the results to the answers in you
test data, and wrap it in a nice cover page.

Am I the only one who read the assignment?
