After I run it, it doesn't give me the right values. Where can I add the requirements of (when I run it):
"Please enter the amount from W2 form: 8500
Please enter the interest income: 0
Please enter the paid tax amount: -10
Invalid amount. It cannot be negative.
Please enter the paid tax amount: -5
Invalid amount. It cannot be negative.
Please enter the paid tax amount: 15000
Invalid amount. It cannot be greater than your total income.
Please enter the paid tax amount: 400
Please enter the amount for deduction: 250
- Added input validation checks for paidTax to ensure it's not negative and not greater than the total income and interest.
- Moved the declaration of
income,interest,deduction, andpaidTaxvariables inside thedoloop to allow for re-entry of values when there's an invalid input. - Updated the printed values to use the actual user input instead of hardcoded values.
Now, the program will prompt the user for inputs as specified and validate them before proceeding with calculations.
