1a) [30 marks] A company has four salespeople who sell five different products. Each salesperson passes in slips for each different type of product sold. Each slip contains the following:
a) The salesperson number b) The product number c) The total price of that product sold that day by that salesperson.
Assume that 10 slips are available. Write a program that reads all this information and summarize the total sales by salesperson by product. All totals should be stored in the two-dimensional array sales. After processing all the sales information, print the results in tabular format with each of the columns representing a particular product and each of the rows representing a particular salesperson. Cross total each row to get the total sales of each product; cross total each column to get the total sales by salesperson. Your tabular printout should include these cross totals to the right of the totaled rows and to the bottom of the totaled columns.
