Yes—the list shows what must be done, in general terms. Once the plan is complete, it can be followed in several ways.
Here is another program that follows the plan:
' Get the number of Miles PRINT "How many miles were traveled" INPUT MILES ' ' Get the number of Gallons PRINT "How many gallons were used" INPUT GALLONS ' 'Calculate and print miles per gallon PRINT MILES / GALLONS, "Miles per Gallon" ' END
Now the first two tasks of the plan take two statements each. The flowchart is unchanged, since its boxes shows in general terms what each task does.
A user of the program might want to enter the beginning odometer reading and the ending odometer reading, and have the program calculate the number of miles traveled. Does the plan need to be modified to show this new feature?
