(Misc. application)

a. The data in the following chart was collected on a recent automobile trip:

Mileage	Gallons
22,495	Full tank
22,841	12.2
23,185	11.3
23,400	10.5
23,772	11.0
24,055	12.2
24,434	14.7
24,804	14.3
25,276	15.2

Write a C++ program that accepts a mileage and gallons value and calculates the miles per gallon (mpg) for that segment of the trip. The mpg is obtained as the difference in mileage between fill-ups divided by the number of gallons of gasoline used in the fill-up.

---

b. Modify the program written for Exercise a to also compute and display the cumulative mpg after each fill-up. The cumulative mpg is calculated as the difference between the mileage at each fill-up and the mileage at the start of the trip divided by the sum of gallons used to that point in the trip.
