Weekly Salary Computation

/******************************************************

** Name: 

** Filename: weeklysalary.cpp

** Project #: 

** Project Description: A company pays its employees as managers
   (who receive a fixed weekly salary), hourly workers (who recieve a
   fixed hourly wage for up to the first 40 hours they work and "time-
   and-a-half," i.e., 1.5 times their hourly wage, for overtime hours
   worked), commission workers (who receive $250 plus 5.7% of their
   gross weekly sales), or pieceworkers (who receive a fixed amount of 
   money per item for each of the items they produce--each pieceworker
   in this company works on only one type of item). Write a program to
   compute the weekly pay for each employee. You do not know the number
   of employees in advance. Each type of employee has its own pay code:
   Managers have paycode 1, hourly workers have code 2, commission 
   workers have code 3 and pieceworkers have code 4. Use a switch to 
   compute each employee's pay based on that employee's paycode. Within
   the switch, prompt the user (i.e., the payroll clerk) to enter the 
   appropriate facts your program needs to calculate each employee's
   pay based on that employee's paycode.

** Output:The number of total employees paid.
          The number of Managers paid.
		  The number of Hourly workers paid.
		  The number of Commission workers paid.
		  The number of Piece Workers paid.

** Input: Paycode of employee.
          Code 1:(Manager Info)
		   - Weekly Salary
		  Code 2:(Hourly Worker Info)
		   - Hourly Salary
		   - Hours Worked
		  Code 3:(Commission Worker Info)
		   - Gross Weekly Sales
		  Code 4:(Piece Worker Info)
		   - Number of Pieces
		   - Wages per Piece

** Algorithm: Instruct user of programs purpose.
              List paycodes and instruct user to enter a paycode
			  or press -1 to end program.
			  When paycode is entered go to the case in the switch
			  which will compute the pay for that worker.
			  Each time a paycode is used count the number of times.
			  When -1 is pressed instead of paycode then print out 
			  the total number of employees to be paid.
			   -List# of:
			    -Managers
				-Hourly Workers
				-Commission Workers
				-Piece Workers
              End Program
