- Use C++ language Create a class called Fraction for performing arithmetic with fractions. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor function that enables an object of this class to be initialized when it is declared. The constructor should contain default values in case no initializers are provided. Provide public member functions for each of the following: a) Addition of two Fraction numbers (included in the Frac.cpp as an example). b) Subtraction of two Fraction numbers. c) Multiplication of two Fraction numbers. d) Division of two Fraction numbers. e) Printing Fraction numbers in the form a/b where a is the numerator and b is the denominator. f) Printing Fraction numbers in double floating-point format.Assume that class B is derived publicly from class A. Class A has two functions, f1() and f2(). Function f2() is virtual. Assume the following statements statements:A* ptr=new B; ptr->f1(); ptr->f2(); Fill in the blank.The function f1() as defined in class ____ will be used. The function f2() as defined in class _____ will be used. In question 1, the call to ptr->f2() is an example of _______________________.True or false? (1) You can redefine a private function defined in a base class. (2) You can redefine a static function defined in a base class. (3) You can redefine a constructor.
- Exercise 4: Define a class BOOK with the following specifications: Private members of the class BOOK are BOOK NO integer type BOOKTITLE 20 characters float (price per copy) A function to calculate the total cost for N number of copies where N PRICE TOTAL_COST() is passed to the function as argument. Public members of the class BOOK are INPUT() function to read BOOK_NO. BOOKTITLE, PRICE PURCHASE() function to ask the user to input the number of copies to be purchased. It invokes TOTAL_COST() and prints the total cost to be paid by the user. Note: You are also required to give detailed function definitions.oop using c++ please give me full answer thanks Write a class Currency and makes the following attribute and member function. Currency name (String) Make a function name converter which converts the currency. Display function which display the value Make 3 derived classes name Dollar, euro and yen from Class Currency. In dollar class make a function converter and converts the minimum 50 dollars in rupees. In euro class make a function name converter which converts 1000 rupees into euro. User enter the amount less than 1000 display error message” invalid amount” Also create getter, setter and default constructor in above task.14. Assume that class B is derived publicly from class A.

- C++ Personal Information Class: Design a class that holds the following personal data: name, age, and phone number. Write appropriate accessor and mutator functions. Demonstrate the class by writing a program that creates three instances of it. One instance should hold your information, and the other two should hold your friend's or family member's information.Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)(Program) a. Complete the following class by including functions corresponding to the two prototypes listed in the declaration section: classElevatorprivate:intelNum;//elevatornumberintcurrentFloor;//currentfloorinthighestFloor;//highestfloorpublic:Elevator( int=1,int=1,int=15);//constructorvoidrequest( int);; In this definition, the data member elNum is used to store the elevator’s number, the data member currentFloor is used to store the elevator’s current floor position, and the data member highestFloor is used to store the highest floor the elevator can reach.The constructor should allow initialization of an object’s three data members with the data passed to the constructor when an Elevator object is instantiated. The request function should code the following algorithm: If a request is made for a nonexistent floor, a floor higher than the topmost floor, or the current floor Do nothing ElseIf the request is for a floor above the current floor Display the current floor number While not at the designated floor Increment the floor number Display the new floor number EndWhile Display the ending floor number Else // the request must be for a floor below the current floor Display the current floor number While not at the designated floor Decrement the floor number Display the new floor number EndWhile Display the ending floor number EndIf b. Include the class written for Exercise 3a in a complete program, and verify that all member functions work correctly.
