Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…

Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…
True or False A child class cannot override the parent’s definition of an inherited method.
