A destructor function is called automatically when the object goes out of scope:
I. the function ends
II. the program ends
III. a block containing local variables ends
When you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class.

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:

- True or false: A class object can be passed to a function, but cannot be returned by a function.arrow_forwardSummary 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".

- JVarrow_forwardWhich 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.
