In python, create a LunchOrder application that prompts the user for the number of hamburgers, salads, french fries, and sodas and then displays the total for the order. The LunchOrder application should includea Food object with a constructor that accepts the price, fat, carbs, and fiber for an item. Food methods should return the price of the item and return the fat, carbohydrates, and fiber. Use the chart below forfood prices and nutrition information:
Summary
In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status.
Instructions
Open the file named Motorcycle.py.
Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method.
In theMotorcycle class, create an attribute named sidecar.
Write a public set method to set the value for sidecar.
Write a public get method to retrieve the value of sidecar.
Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast".
Open the file named MyMotorcycleClassProgram.py.

C++HurdleGame The HurdleGame class contains all the functions invoked as a result of a user action (i.e. when a user presses a key on the Hurdle Frontend, one of the functions in HurdleGame will be called. A HurdleGame object comprises a HurdleWords object (which stores all valid guesses and valid Hurdles), and a HurdleState object, which stores and tracks all the game states. Any action should update the HurdleState object.Each function in HurdleGame is called as a result of a user action on the Hurdle Frontend. To understand this, please read the Hurdle Backend API section below before implementing. You are responsible for implementing each of the functions below. LetterEntered ● Called by the Hurdle frontend when the user enters a letter. ● Hint: when a user enters a letter, how should the underlying HurdleState be modified to reflect the change resulting from that key press? WordSubmitted ● Called by the Hurdle front end when the user submits a guess by pressing enter. ● Hint: when…

- Which statement is false? Select one: a. The compiler always creates a default constructor for a class. O b.If a class has constructors, but none of the public constructors are no- argument constructors, and a program attempts to call a no-argument constructor to initialize an object of he class, a compilation error occurs. O c.A constructor can be called with no arguments only if the class does not have any constructors or if the class has a public no-argument constructor. O d.

Diamond, Emerald and Gold. Diamond is 100 points, Emerald 70 points and Gold is 50 points.There are thieves in the game that will prevent you from hunting for treasure. Encountering a thief they steal some of your treasure. You will randomly generate which thief will steal from which treasure and how much.At the beginning of the game, the player has no treasure. X, Y, Z and H will be randomly identified at the start of the game.
