Create each bar in the bar chart by displaying a row of asterisks. Each asterisk should represent $100 of sales. Here is an example of the program’s output:   Enter today's sales for store 1: 1000 [Enter] Enter today's sales for store 2: 1200 [Enter] Enter today's sales for store 3: 1800 [Enter] Enter today's sales for store 4: 800 [Enter] Enter today's sales for store 5: 1900 [Enter]   SALES BAR CHART Store 1: ********** Store 2: ************ Store 3: ****************** Store 4: ******** Store 5: *******************
