Use a twodimensional array to solve the following problem A

Use a two-dimensional array to solve the following problem: A company has four salespeople - Sales Person 1, Sales Person 2, Sales Person 3. and Sales Person 4. The company sells 5 products - Product 1, Product 2, Product 3, Product 4, and Product 5. Each day, a sales person hands in a slip with the following information: Sales Person Number (1-4), Product Number (1-5), and dollar value of that product sold. This dollar value should be entered in the appropriate place in the multi-dimensional array. Keep asking for data input until a -1 is entered for the sales person number (sentinel). Output: Your output should reflect the array in tabular format ALONG with cross-sectional totals. For example, your program should look something like this: Enter Sales Person Number (1-4) or-1 to quit and view data: 1 Enter the Product Number (1-5): 1 Enter the dollar value: 1000 Enter Sales Person Number (1-4) or -1 to quit and view data: 2 Enter the Product Number (1-5): 1 Enter the dollar value: 2000 Enter Sales Person Number (1-4) or-1 to quit and view data: 2 Enter the Product Number (1-5): 2 Enter the dollar value: 500 Enter Sales Person Number (1-4) or-1 to quit and view data: -1 Sales Person Product 1 Product 2 Product 3 Product 4 Product 5 Sales Person Totals
