Question

C++ Program

A company pays its salespeople on a commission basis.  The salespeople each receive $250 per week plus 11 percent of their gross sales for the sales period.  For example, a salesperson who grosses $5000 in sales in the period receives $250 plus 11 percent of $5000, or a total of $812.21.  Write a program (using an array of counters) determines for each salesperson their total sales, their salary and additional data points.  There are 12 salesmen for the company.  The input data file is "SalesPerson SalesV3.txt". It contains the salesperson number (3 digit id) followed by his sales.   Each salesperson has numerous sales listed for the period.  You will need to keep up with the total number of sales and of course the total sales per salesman.

Output :  

             1. Print out the Sales report showing the salesmen ID, his total number of sales, his total sales      
and his average per sale.  Show the report in sorted ordered by Sales ID.

    2.  Print out the same report but this time print out in sorted ordered by total sales.

    3.  Print out the same report again sorted on average sales.

The company is looking at a reduction in sales force.  So I need to know which salesman had the smallest total sales.  Print out the worsted salesman, his total sales and percentage of his sales compared to the second worsted salesman.  (Just to see how off his sales really are compared to one other. ie did he have a bad sales period or he is really a bad salesman.)
