Code Problem 2

Write a program that determines the income tax rates for a state.  Tax rates are based on the salary according to the following table:

0 – 25000 Dollars                    10%

25001 - 50000 Dollars            15%

50001 - 75000 Dollars             20%

Over 75000 Dollars                 35%

Write the program so that it asks the user how many taxpayers should be processed and use the number of taxpayers to control the end of the program. For each taxpayer, you will need to input the taxpayer ID and salary. Use a while loop to validate the taxpayer ID to make sure that it is a number that does not exceed 6 digits in length. Display the following message for an invalid taxpayer ID length: Invalid taxpayerID. Please enter a number that is < 7 digits. Display the taxpayer ID, salary, tax percent, and taxes owed for each taxpayer processed within the loop. Taxes owed is calculated by multiplying the salary * tax % (depending on how you write the program you may need to divide the tax % by 100) when calculating the taxes owed. Use a printf command to display the output in  2 columns and make sure that the percents are formatted with 1 decimal place and the salary and taxes owed are formatted with 2 decimal places. When the program ends, a message of Earn money. Pay taxes. Enjoy life! should be displayed. To help you test your program, below is should run with 4 test cases and no invalid taxpayer IDs:

Be sure to include comments at the top of your program to indicate your name and the name of the program and date.

Please enter the number of taxpayers you want to process.
