The program inExample 5-4 uses a sentinel control loop to process cookies sales data.

Assume that the data is provided in a file calledCh5_Ex18Data.txt and the first line in the file specifies the cost of one box.

Modify the program (inmain.cpp) so that it uses an EOF-controlled loop to process the data.
