Use a two dimensional array to solve the following problem. A company has four salespeople ( 1 to 4) who sell five different products ( 1 to 5).

Once a day, each salesperson passes in a slip for each different type of product sold. Each slip contains the following:

a) The salespersons number
b) The product number
c) The total value of the product sold that day.

Thus, each salesperson passes in between 0 and 5 slips per day. Assume that the information from all the slips for last month is available.

Write a program that will read all this information for last month sales and summarize the total sales by salesperson by product. All totals should be stored in the two dimensional-array Sales. After processing all the information for last month, print the results in tabular format with each of the columns representing a particular salesperson and each of the rows representing a particular product. Cross total each row to get the total sales of each product for last month; cross total each column to get the total sales by salesperson 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

Note: I have provided a data file that must be used for this assignment.

Here is a link to the file problem_7-20.txt

Here is the layout for the data file: salesperson product number total sales
salesperson and product number are integers, total sales is a real number.

You may need to refer back to the information I posted on Strings and File Input/Output on my web site.
