Tax Calculator

[ekat90]

Doing another assignment that I'm currently having a little trouble with at the moment, we need to create a tax calculation program that will total incomes, total expenses and calculate the tax payable.

Now I'm able to give the user added incomes, but it requires me too create many different variables, and giving addition too all those variables, I'm sure there's a easier and cleaner way that I don't know how to do it from.

Here's a video my mentor has given me as a demonstration.

Also I have a link too what I could come up with right now.

from what i figured out you add your incomes till you hit the "-" key and hitting "ok" takes you too the next step the "expenses" once you've done this it subtracts the total amount, like for example income-expense=tax payable(taxable income)

With this total amount we need the program too give us a maths calculation through this table that my mentor gave me:

Taxable Income $ ----------- Tax on this income
$ 0-18200 ----------- $0
$ 18201-37000 ----------- $19cents for each $1 over 18200
$37001-80000 ----------- $3572+32.5cents for each $1 over 37000
$80001-180,000 ----------- $17547 plus 37cents for each $1 over 80000
$180,001 and over ----------- $54547 plus 45cents for each $1 over 180,000

So far I've gotten a massive headache on trying too get this thing right and its killing me right now, if anyone could possible divide some time to help a programmer in frustration just trying to learn to get this thing right, I would appreciate it alot!

if anyone can help me put this program together asap I'm giving out donations to whoever helps, im really desperate.

Looking At the problem, you do not need any variables to hold the tax just a number of nested if/ else statements to calculate the tax for each bracket. The easiest way is to start with the top bracket and work your way down.
If income is > 180000
return 54547 + 0.45 * income-180000
else
if income > 80000
...
So create a function that transverses the tree until the income (passed in as a parameter to the function) matches the if statement, then the tax is computed and returned

Building two While loops that look for a negative number to stop requires only two variables to hold the summations.
After that you can use the two variables to compute the taxable profits variable, and use that variable a few If statements to do the rest.
