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?

In this lab, you complete a prewritten c++ program for a carpenter who creates personalized house signs. the program is supposed to compute the price of any sign a customer orders, based on the following facts: the charge for all signs is a minimum of $35.00. the first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. if the sign is made of oak, add $20.00. no charge is added for pine. black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. instructions ensure the file named housesign.cppis open in the code editor. you need to declare variables for the following, and initialize them where specified: a variable for the cost of the sign initialized to 0.00 (charge). a variable for the number of characters initialized to 8 (numchars). a variable for the color of the characters initialized to "gold" (color). a variable for the wood type initialized to "oak" (woodtype). write the rest of the program using assignment statements and ifstatements as appropriate. the output statements are written for you. execute the program by clicking the run button. your output should be: the charge for this sign is $82. this is the code, // housesign.cpp - this program calculates prices for custom made signs. #include #include using namespace std; int main() { // this is the work done in the housekeeping() function // declare and initialize variables here // charge for this sign // color of characters in sign // number of characters in sign // type of wood // this is the work done in the detailloop() function // write assignment and if statements here // this is the work done in the endofjob() function // output charge for this sign cout < < "the charge for this sign is $" < < charge < < endl; return(0); }

Two technicians are discussing the common u-joint. technician a says its input and output speeds should be equal. technician b says that it normally has two yokes. which technician is correct?

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)
