Here are the directions for my C++ assignment:

Declare and define a C++ class called odometer that will track miles driven and gallons used by a vehicle. The class should have member variables for total miles driven and gallons consumed. Include the following mutator functions in your class:

miles driven and gallons of gas consumed

reset odometer to zero

reset gallons

Include the following accessor functions in your class:

return fuel efficiency in miles per gallon (MPG)

return odometer reading (total miles driven since the last reset)

Your class declaration should be in a header file with inclusion guards. Your class implementation should be in a cpp file.

Create a driver (main) program to test your class. Your driver program should be in a separate cpp file.

You may create a default constructor for this assignment OR rely on the automatically created default constructor

*** I'm attempting to achieve this desired output. It's updating the total miles driven in the first two, and then it resets right before the third update. ***

Here's the the main.cpp file which contains my main driver:

#include #include "odometer.h" using namespace std;

int main() { odometer o; o.setMilesAndGallons(100,10); cout

Here's the odometer.cpp file which contains my function definitions:

#include #include "odometer.h" using namespace std;

odometer::odometer() { totalMilesDriven=0; gallonsUsed=0; } //mutator method to set miles and gallons void odometer::setMilesAndGallons(long milesDriven, long usedGallons) { totalMilesDriven= milesDriven; gallonsUsed= usedGallons; } //reset the miles and gallons to zero void odometer::resetToZero() { gallonsUsed=0; totalMilesDriven=0; } //mutator function to reset the gallons void odometer::resetGallons() { gallonsUsed=0; } //method to check the fuel efficiency double odometer::fuelEff() { return (double)((double)totalMilesDriven / (double)gallonsUsed); } // method to get odometer reading long odometer::odometerReading() { return totalMilesDriven; }

Here's the odometer.h header file which contains my class:

#include #ifndef ODOMETER_H #define ODOMETER_H

class odometer { //private member variables for storing miles and gallons private: long totalMilesDriven; long gallonsUsed; public: //using default constructor odometer(); //mutator method to set miles and gallons void setMilesAndGallons(long totalMilesDriven, long gallonsUsed); //reset the miles and gallons to zero void resetToZero(); //mutator function to reset the gallons void resetGallons(); //method to check the fuel efficiency double fuelEff(); // method to get odometer reading long odometerReading();

};

#endif // ODOMETER_H

Here's my current output:

Total Miles Driven: 253 Gallons Consumed: 10 Miles Per Gallon: 25.3 Total Miles Driven: 566 Gallons Consumed: 25 Miles Per Gallon: 22.64 Total Miles Driven: 291 Gallons Consumed: 13 Miles Per Gallon: 22.3846 Process exited after 0.0238 seconds with re Press any key to continue..
