Problem Statement:
Use a double-subscripted array to solve the following problem. A company has four salespeople (numbered 1 to 4) who sell five different products (numbered 1 to 5). Once a day, each salesperson passes in a slip for each different type of product sold. Each slip contains
1. The salesperson numberWrite a program that reads in (from the user) all the information from the previous month's sales. Your program should read in information until the user is finished entering (they will indicate this by entering the sentinel value -1 for the salesperson number) and summarize the total sales by salesperson and product. After processing the information, your program should print the results in a tabular format with each of the rows representing a particular salesperson and each of the columns representing a particular person. Cross total each row to get the total sales of each product for last month; cross total each column to get the total sales of each product for last month. Your tabular printout should include these cross totals to the right of the totaled rows and to the bottom of the totaled columns.
2. The product number
3. The total dollar value of that product sold on that day.Sample Run:
