Total Sales

A company has four salespeople who sells five different products.Once a day, each salespeople passes in a slip for each different type of product sold.Each slip contains:

• The salespeople number
• The product number
• The total dollar value of that product sold that day

The program below will read all the information for last month's sales and summarize the total sales by salespeople by product and then print the result in a tabular format.
