For this assignment you will write a program that calculates payroll information for hourly and salaried employees (2 separate categories).

Your program should begin by displaying a brief set of instructions to the user. Then ask if the user wishes to continue or not. Do not use the exit() function if the user does not wish to continue, but rather code a loop whose body executes as long as the user's choice (to continue) is "y" or "Y". (Hint: use a pattern 1 loop.)  The user should be able to enter any number of payroll calculation requests. After each request, input of data, and display of results, the program will ask if another calculation is desired. When the user finally enters something other than "y" or "Y", the program will terminate.

For each payroll calculation request, your program should do the following:

• Ask if this calculation is for an hourly or salaried employee. The user must enter "h" or "H" or "s" or "S". Do not let the user continue until one of these is entered.
• If the calculation is for an hourly employee, prompt for and obtain:
  • a daily base salary
  • a bonus (could be $0.00)
  • the number of days in this month
• then calculate
  • gross salary = base salary * days in the month + bonus
  • tax amount = gross salary * tax rate
  • net salary = gross salary - tax amount
• then display gross salary, tax amount, and net salary (labeled for "Hourly Employee")
• Otherwise, the calculation must be for a salaried employee, so prompt for and obtain:
  • the monthly salary
• then calculate
  • gross salary = monthly salary
  • tax amount = gross salary * tax rate
  • net salary = gross salary - tax amount
• then display gross salary, tax amount, and net salary (labeled for "Salaried Employee")
• ask the user if another payroll calculation is desired, and accept the answer.

Notes:

1. Use a symbolic constant to specify the tax rate.  Use a value of 0.08.

2. It is suggested that you develop your program incrementally. Don't write it all out on paper and then try to type it in and compile and debug it at once. Try a bit at a time. For example:

• first do just the opening instructions to the user.
• add the main loop that exits on a non-"y" or "Y". Put a single cout in the loop to say "in the main loop" and the prompt to continue or quit at the bottom of the loop and the instruction to get the user's response.
• add code in the loop to accept a "h" or "H" or "s" or "S". If the user types anything else, display an error message and accept a new try. This itself is a little loop within the big payroll calculation loop. (Hint: try a do..while for this.) Use a bool variable called ok to decide whether or not to display a "retry" message and to control exit from this loop.
• add code to do salaried workers since this case is simpler. Test the program just on this choice.
• add code to determine if the user chose salaried or hourly workers, and execute one branch or the other. Just put a cout() in the hourly-based branch for now ("in hourly calc branch")
• add code to prompt for and get the needed information for hourly workers.

In general, this incremental approach is more efficient (i.e. you will have fewer errors and finish sooner). If you have an error, it will probably be in the bit of code you just added, and will be easier to find. Try to learn to think about how to adopt this approach in all the programs you do.

3. Notice that this program contains structures inside structures (loops in loops, decisions in loops, etc.) Be very careful about how you code these structures - especially in beginning and ending blocks with {} pairs and in formatting the code carefully. Pay attention to standard indenting of loop bodies and decision blocks. Each new level of "nesting" needs a new level of indenting.

4. Document your program according to the course Documentation Standards. Use appropriate numeric data types. These instructions should be considered standard for all subsequent programs.
