Control structures

I am asked to generate a set of INPUT TEST VALUES. Is that included into this control structure, or do I have to create a whole different set of variables?

(if you have to create an extended set of variables please return posting so I can add more credits.)

Declared Variables

Input: salary in real
Output: tax in real
Other: baseTax in real, minimum in real, Excess in real

Control Structure: if-then-else (dual alternative)

Method Taxation:
Begin
If salary is negative exit with error

If salary <= 1499.99 then
Minimum = 0
baseTax = 0
Excess = 0.15
tax = calculateTax(minimum, baseTax, Excess, salary)

Else If salary <= 2999.99 then
Minimum = 1500
baseTax = 225
Excess = 0.16
tax = calculateTax(minimum, baseTax, Excess, salary)

Else If salary <= 4999.99 then
Minimum = 3000
baseTax = 465
Excess = 0.18
tax = calculateTax(minimum, baseTax, Excess, salary)

Else If salary <= 7999.99 then
Minimum = 5000
baseTax = 825
Excess = 0.20
tax = calculateTax(minimum, baseTax, Excess, salary)

Else If salary <= 14999.99 then
Minimum = 8000
baseTax = 1425
Excess = 0.25
tax = calculateTax(minimum, baseTax, Excess, salary)

showTax()

End Taxation

Subroutine calculateTax:
calculateTax(baseTax, salary)
Begin
Tax = baseTax + (salary – minimum) * Excess
Return Tax
End calculateTax

Subroutine showTax:
showTax()
Begin
Print “The Tax amount is ”, tax
End
