CS170 Tax Return Processing

Requirements:

The company that needed the flowchart and pseudocode for calculating the Tax Owed amount for tax returns is now giving you the responsibility of creating a program for that purpose.

The requirements for performing the calculation remain the same as those indicated for the flowchart:

For citizens younger than 21, the tax applied is one of the following:

8% for income up to $20,000.
12% for income greater than $20,000 up to $50,000.
20% for income greater than $50,000.

For citizens 21 years old or older, the tax applied is one of the following:

10% for income up to $20,000.
15% for income greater than $20,000 up to $35,000.
25% for income greater than $35,000 up to $70,000.
30% for income greater than $70,000.

The formula to calculate the Tax Owed amount is:

tax rate percentage x income

Additional Requirements:

• You will enter a comment on the head section with your name on it.
• You will use radio buttons to acquire the age range of the user.
• You will use a text box to get the user's income data.
• You will use a Process button to process the Tax Owed amount.
• The button mentioned above should also:
  • Produce an error message (via an alert window) if the user forgets to select a radio button.
  • Produce an error message (via an alert window) if the user forgets to enter income data or enters data that cannot be processed such as text data.
• You will use text box to display the tax owed amount.
• You will use a Clear button to reset the main variables as well as the radio buttons and text boxes in order to be able to process the next user's information.
• The variable names should be descriptive. For example, if a program is calculating the tip given at a restaurant, an appropriate variable name may be tipAmount.
