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.
- Create a class Rational for performing arithmetic with fractions.Write a driver program to test the class. Provide a constructor thatenables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in caseno initializes are provided and should store the fraction in reducedform. Provide a private function to reduce numbers.Provide Public member functions for each of the followingarithmatic’s functions (addition – subtraction – multiplication –division), printing in the form a/b, printing in floating point formatand final overload the == and != operators to allow comparisons oftwo fraction numbers.Include any additional operations that you think would be useful fora rational number class.Design, implement, and test your class.
(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.
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)
Using C++ 11(do not use string data type) Create a class called Complex for performing arithmetic with complex numbers. Write a program to test your class. Complex numbers have the form: realPart + imaginaryPart * i Where i is − 1 Use double variables to represent the private data of the class. Provide a constructor 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 that perform the following tasks: a) Adding two complex numbers: The real parts added together and the imaginary parts are added together. You should pass two objects to your function. b) Subtracting two complex numbers: The real parts subtracted together and the imaginary parts are subtracted together. You should pass two objects to your function. c) Printing Complex numbers in the form (a , b), where a is the real part and b is the imaginary part. (Do not use operator overloading…

Need C# code Consider the following class definition that represents an AM radio: class Radio { public bool isSwitchedOn; // either true or false public int volume; // from 0 to 10 public double frequency; // from 535 to 1605 Mhz } Provide a redesigned radio class that uses more appropriate member access operators Provide signatures for two mutator (setter) methods that will enable the two instance variables to be changed through an object of the class Write bodies for the mutator (setter) methods for which you provided signatures in question (b), above. The implemented methods must prevent the two instance variables from being set to invalid values. Return a boolean flag to indicate the success/failure of the requested operation Provide a constructor for the radio class that will initialize the instance variables to suitable (valid) start values. Write a short test harness that instantiates the radio class and demonstrates that the setter methods you designed above behave…
Consider the following statements: A. Constructor is a member function of the class. B. The compiler always provides a zero argument constructor. C. It is necessary that a constructor in a class should always be public.
ABC Bank announced a new scheme of reward points for a transaction using an ATM card. Each transaction using the normal card will be provided by giving a reward percentage of the transaction amount as a reward point. If a transaction is made using a premium card and it is for fuel expenses, additional 10 points will be rewarded. Write a program to calculate the total reward points.Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.A class VISACard has the following attributes. Access Specifiers Data type Variable protected string type protected double amount private int rewardPercentage Include the following method in VISACard class.

Using C++ Define a class fruitType to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int). Declare a variable of type fruitType to store the following data: Fruit name—banana, color—yellow, fat—1, sugar—15, carbohydrate—22. Write a member function, setFruitInfo to store data into a variable of fruitType. Write a member function, getFruitInfo to get data from a variable of fruitType. Write a member function, printFruitInfo to output data stored into a variable of fruitType. Use appropriate labels to identify each component. Test your solution by calling all funtions.
