Create an application in C# 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 the ++ 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.

this is what i have:

using static System. Console;

class CarDemo

{

static void Main()

{

Car c1 = new Car("Camero", 25);

Car c2 = new Car("Mustang");

Display("Camero at beginning", c1);

++c1;

Display("Camero after prefix increment", c1);

Display("Mustang at beginning", c2);

++c2;

Display("Mustang after prefix increment", c2);

}

public static void Display(string message, Car)

{

WriteLine(Mpg);

}

class Car

{

private string Model

{

get

{

return model;

}

set

{

model = value;

}

}

private double Mpg

{

get

{

return mpg;

}

set

{

mpg = value;

}

}

public Car(string model, double mpg)

{

Model = model;

Mpg = mpg;

}

public Car(string model)

{

Model = model;

Mpg = 20;

}

public static Car operator++(Car c)

{

++c. Mpg;

return c;

}

}

}

what am i doing wrong?
