- Does a static member variable come into existence in memory before, at the same time as, or after any instances of its class?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:…What is the order of Constructors call when the object of derived class child is declared, provided class child is derived from class parent? Select one: a.Constructor of child only b.Constructor of child followed by parent c.Constructor of parent followed by child d.Constructor of parent only
- What statements about the destructor of an object are accurate? a. The destructor of a class is a member function that is automatically activated when an object becomes inaccessible. b. The destructor has no arguments and its name must be the character ~ followed by the class name (e.g., ~bag for the bag class). c. Because the destructor is automatically called, programs rarely make explicit calls to the destructor, and we generally omit the destructor from the documentation that tells how to use the class. d. The primary responsibility of the destructor is simply releasing dynamic memory. c & d a, b, & c b & c a & b a, b, c, & dIn a class with overloaded constructors, each version of the constructor must have a differentDefine Invoking a Constructor.
- What is the order of Destructors call when the object of derived class child is declared, provided class child is derived from class parent? Select one: a.Destructor of parent only b.Destructor of child followed by parent c.Destructor of parent followed by child d.Destructor of child onlyHow we can access protected data members of a class without the use of public or private functions? Explain with codeJust what are "static members" of a class? When and how should you use them, exactly?
