Question

A company has three salespeople (1 to 3) who sell five different products (1 to 5). Once a day, each saleperson passes in a slip for each type of product sold. Each slip contains the following: a) The salesperson number b) The product number c) The total dollar value of that product sold that day Thus, each salesperson passes in between 0 and 5 sales slips per day. Assume that the information from all of the slips for last month is available. You are required to write a C# program that will read all the information for last month’s sales and summarize the total sales by salesperson and by product. All sales data should be stored in a two-dimensional array sales. After processing all the information for last month, display the results in tabular format, with each column representing a particular 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 salesperson for last month. You tabular output should include these cross-totals to the right of the totaled rows and below the totaled columns.

A sample output is as follows:

Enter sales person number (-1 to end): 1

Enter product number: 100

Enter sales amount: 1000

Invalid input!

Enter sales person number (-1 to end): 1

Enter product number: 1

Enter sales amount: 100

Enter sales person number (-1 to end): 1

Enter product number: 3

Enter sales amount: 200

Enter sales person number (-1 to end): 1

Enter product number: 5

Enter sales amount: 300

Enter sales person number (-1 to end): 2

Enter product number: 2

Enter sales amount: 400

Enter sales person number (-1 to end): 2

Enter product number: 4

Enter sales amount: 500

Enter sales person number (-1 to end): 3

Enter product number: 1

Enter sales amount: 600

Enter sales person number (-1 to end): 3

Enter product number: 2

Enter sales amount: 700

Enter sales person number (-1 to end): 3

Enter product number: 3

Enter sales amount: 800

Enter sales person number (-1 to end): -1

Product Salesperson 1 Salesperson 2 Salesperson 3 Total

1 $100.00 $0.00 $600.00 $700.00

2 $0.00 $400.00   $700.00 $1,100.00

3 $200.00 $0.00 $800.00 $1,000.00

4 $0.00 $500.00 $0.00 $500.00

5 $300.00 $0.00 $0.00   $300.00

Total $600.00 $900.00 $2,100.00
