The class definition and function prototypes are in the provided car.h header file. A testing program is in the provided main.cpp file. You don't need to change anything in car.h or main.cpp. Submission: Submit the completed car.cpp file and a screenshot of your output on Blackboard. Due: Friday, February 15h, 2019, end of day. The Car class has the following: private data and helper functions that are only accessible by the class member functions: mpg-how many miles the car can go on a gallon of fuel mileage-the current number of miles on the car's odometer availableFuel-the current number of gallons of fuel in the car's tank fuelCapacity-the maximum number of gallons of fuel that can go in the car's tank add Mi les-this adds miles to the data member mi 1e age useFuel-this subtracts gallons of fuel from the data member availableFuel publicly available functions: Car default constructor-this is defined in car.h, you don't need to define in car.cpp Car custom constructor-takes in values to initialize mpg and fuelCapacity getMileage-returns the current value of data member mileage getAvailableFuel-returns the current value of data member availableFuel getFuelCapacityreturns the current value of fuelCapacity drive-takes in a number of miles for the trip as a parameter. It will first calculate the number of gallons of fuel needed for the trip given the number of miles and the car's mpg. If the number of gallons needed exceeds the gallons available, the function will return a value of false. If the number of gallons needed is available, drive will call the helper addMiles function with the number of miles driven, call the helper useFuel function with the number of gallons used, and return a value of true. refuel-will set the value of data member availableFuel to the value of data member fuelCapacity Sample output: See the following screenshot for sample output using the provided main.cpp testing program. Enter miles for trip 1: 78 Trip 1 not taken. Need to refuel. Current fuel level: 2.00 New fuel level: 24.50 Enter miles for trip 2: 45 **Trip 2 taken.* Miles driven: 45.00 Starting mileage: 5.00 Ending mileage: 50.00 Gallons used: 2.50 Gallons renaining 22.00 Enter miles for trip 3: 67 **Trip 3 taken.** Miles driven: 67.00 Starting mileage: 50.00 Ending mileage: 117.00 Gallons used: 3.72 Gallons remaining 18.28
