Adapt this program to accept input pairs old price/new price for multiple products, from a text le. Your products.txt text le should contain 5 records (lines), each line consisting of 3 elds: product name (string), old price (float), and new price (float). Reading from the text le should be controlled by EOF, not by the number of lines known beforehand. As the program reads from the le, a counter variable should keep track of the number of records read. This variable should be used later for calculating the average ination rate, derived as a simple average of the 5 values for the ination rate that result for each product. For this purpose, the program should maintain a running sum of the ination rates, which will be divided by the number of products, to obtain the average. The program should also calculate the projected prices of each of the 5 products next year, and output all 3 prices into an output.txt le. Add a header for this le, indicating what each eld (column) represents, and format the records so each eld starts at the same tab.
