Use a two dimensional array to solve the following problem: a company has four sales people (1 to 4 ) who sale five different products (1 to 5). Once a day, each sales person passes in a slip for each type of product sold. Each slip contains the following:
A- The sales person number
B- The product number
C- The total dollar value of that product sold that day

Thus, each sales person passes in between 0 and 5 sales slip per day. Assume that the information from all the slips for last month is available. Write an application that will read all this information for last month's sales and summarize the total sales by sales person and by product. All totals should be stored in the two dimensional array sales. After processing all the information for last month, display the results in tabular format with each column representing a salesperson and each row 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 sales person for last month. Your output should include these cross-totals to the right of the totaled rows and to the bottom of the totaled columns.
