Consider the following class definition: (8)class base{public:void setXYZ(int a, int b, int c);void setX(int a);int getX() const { return x; }void setY(int b);int getY() const { return y; }int mystryNum() { return (x * y - z * z); }void print() const;base() {}base(int a, int b, int c);protected:void setZ(int c) { z = c; }void secret();int z = 0;private:int x = 0;int y = 0;};a. Which member functions of the class base are protected?b. Which member functions of the class base are inline?c. Write the statements that derive the class myClass from classbase as a public inheritance.d. Determine which members of class base are private, protected,and public in class myClass.

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:…

Create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate and undergraduate. Out-of-state undergraduate students pay twice the tuition of Florida-resident undergraduate students (all students pay the same health and id fees). A graduate student is either a PhD or a MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Ms and Phd student must be a teaching assistant for one undergraduate course. MS students can only take graduate courses. A course with a Course Number (crn) less than 5000 is considered an undergraduate course, and courses with a 5000 crn or higher are graduate courses.

class GradedActivity { private: double score; public: GradedActivity() { score = 0.0; } GradedActivity(double s) { score = s; } void setScore(double s) { score = s; } double getScore() { return score; } char getLetterGrade() const; }; Implement the GradedActivity class above. In this C++ assignment, create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style.

// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…
