Pretty straight forward.

You will need a set of variables to store the accumulating Miles, and Gallons. As well as an array to store a specific drivers set of miles per gallons. The while loop will allow you to fill and read ("empty") the array to display the results.

Not sure if that was the kind of help you were asking for, let me know if I can be of more help.

I also need help getting started on this same program. But I don't even know where to start...
any help would be great!

How would you begine writing the code...is there a certain format or steps to take in order to compile the program?

I have to do this same program..
this is what I have so far.
but i don't know how to calculate the average miles per gallon or the combined miles per gallon. where and how do I add this into the program. How can i add a sentinel value to determine when u are finished entering input??

#include < iostream.h >

#include < stdio.h >

#include < iomanip.h >



int Miles_traveled(double &g);

double Mileage(int mi,double g);

void Display(double mpg);



void main()

{

int miles;

double gallons,miles_per_gallon;



miles = Miles_traveled(gallons);

miles_per_gallon = Mileage(miles,gallons);

Display(miles_per_gallon);

return;

}



int Miles_traveled(double &g)

{

int mi;



cout << "Please enter the number of miles traveled: ";

cin >> mi;

cout << endl;

cout << "Please enter gallons of fuel burned: ";

cin >> g;

cout << endl;

return mi;

}



double Mileage(int mi,double g)

{

return (double)mi / g;

}



void Display(double mpg)

{

cout << setiosflags(ios::fixed) << setprecision(1);



cout << "According to the data that you have provided, your car
is
getting" << mpg << " miles per gallon.";

cout << endl << endl;

cout << "Hit enter to continue." << endl;

getchar();

return;

}
