Create an application named cardemo that declares at least two car objects and demonstrates how they can be incremented using an overloaded ++ operator.
create a car class that contains the following properties:

- model - the car model (as a string)
- mpg the car's miles per gallon (as a double)

include two overloaded constructors. one accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20.

overload a ++ operator that increases the miles per gallon value by 1. the cardemo application creates at least one car using each constructor and displays the car values both before and after incrementation.

use the following to create the programming exercise:

using static system. console;
class cardemo
{
static void main()
{
// write your main here.
}
public static void display(string message, car s)
{
// write your display() method here.
}
}
