- The distinction between a class's static and non-static data members is as follows: Give an example of real-world application where you think a static data member would be useful.c++ Friend function concepts Do not use operator overloading Create a class Circle with member variable radius R of type float. Create a constructor for assigning value to R and a method "int compare(Circle c)" for comparing the radii. In main method, create two objects of Circle and compare their radii and display which one is biggerC++ Programming Consider the following class implementation, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } bool operator!=(Price); bool operator<(Price); }; Write an implementation for both overloaded operators. != should return true if the Prices are not equivalent, and should return false if they are equivalent. < should return true if the Price of the calling object (left object) is less than the parameter Price object (right object). You do not need to demonstrate calling these operators.
- C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.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.

C++C++ Define and implement a class named Movie with the following members: std::string name; float cost; bool signedByDirector; Movie(); Movie(std::string movietitle); std::string getName (); float getCost(); void setCost (float newCost); // Price is modified by signing (see description) // Change cost to newCost // Returns signedByDirector bool issigned (); void signMovie(); Ensure each variable and function has been set an appropriate access modifier and your header file includes a header guard. Your methodgetCost() should return cost, but if the Movie is signed, it should return the cost plus a markup of 20%. For example, if a movie was worth $100, getCost () should return 100. If the same movie was signed by the author, then getCost() should return 120. Note: This function should not modify the class member cost, instead it should use cost and signedByDirector to determine the actual cost/value of the Movie. Your default constructor should set the cost to 0, the title to "NO TITLE".…class Base { public: int x, y: public: Base(int i, int j) { x = i; y = j; }}; class Derived : public Base public: Derived (int i, int j) { x = i; y = j; void display() {cout « x <<" "<< y; }}; int main(void) { Derived d(5, 5); d.display(); return e; Error O X=5,Y=5 X-0,Y=0 None of the above Other:
