Reading and writing to an excel file.

Sorry I've got no idea whatcha mean there mate sorry.

Like, for example:

  case 5:
    cout << "Enter how many miles per gallon your car does: " << endl;
    cin >> car_mpg;
    cl.setMPG(car_mpg); // Add this type of thing to each of the cases
    break;

to update the object. As at the moment you're not giving it any data.

[rej3kt]

How was I giving it data before the switch statement then?

[Pax]

I assume where you took input was before the point you created the instance of the object.

It worked! Thanks a lot Pax!

Just trying to figure out *why* it works now.

[Pax]

Because when you were saving out to the file, you were taking the value from the "Car" object - which was initialised with variables containing no data. Changing the variables that you used to initialise the car object doesn't make a difference, because the object has made a local copy of them which it maintains itself and doesn't keep in sync with the variables you passed to it.

I don't know if I've explained that very well. :/
