Question

i waan that contain loop and method..

NO DECOMPOSITION WORKSHEET REQUIRED FOR THIS LAB! For this assignment, copy the submission you completed for C12 Eclipse and revise it to read in the data from a file into an array. Use the array to create the Sales Report specified in the previous lab. Display your report by brand name in ascending order Coke 34 3.00 5.00 Sprite 18 2.89 4.30 Fanta Mango 21 3.35 5.99 Orange Crush 35 4.00 6.00 Browns Cream Soda 3 4.25 5.75 Soda Sales Bottles Cost Retail Profit Percent Soda Sold. Bottle Bottle Brand Sold of 150 Totals The total line will tell the company the number of bottles sold the average cost, the average price, the total profit Remember profit is the profht per bottle multiplied by the number of bottles sold.
