Chapter 9, Problem 9.8PE
(The Fan class) Design a class named Fan to represent a fan. The class contains:
- Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed.
- A private int data field named speed that specifies the speed of the fan (the default is SLOW).
- A private boolean data field named on that specifies whether the fan is on (the default is false).
- A private double data field named radius that specifies the radius of the fan (the default is 5).
- A string data field named color that specifies the color of the fan (the default is blue).
- The accessor and mutator methods for all four data fields.
- A no-arg constructor that creates a default fan.
- A method named toString () that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns the fan color and radius along with the string "fan is off' in one combined string.
Draw the UML diagram for the class then implement the class. Write a test

Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…arrow_forwardQ1: Class called (num) and an objeet of this class called (numl).This class contains two data members of type int ( a and b) with private access and two member funetions with public access: Constructor to give value to variables and show_number() to display the sum and multiply of variables. Write a program to set and display the object fields.arrow_forward
- (The Time class) Design a class named Time. The class contains: - The data fields hour, minute, and second that represent a time. - A no-arg constructor that creates a Time object for the current time. (The values of the data fields will represent the current time.) -A constructor that constructs a Time object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. (The values of the data fields will represent this time.) -A constructor that constructs a Time object with the specified hour, minute, and second. - Three getter methods for the data fields hour, minute, and second, respectively. -A method named setTime (long elapseTime) that sets a new time for the object using the elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the minute is 19, and the second is 10. Draw the UML diagram for the class and then implement the class.

Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the resultarrow_forward
- a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z.

PROGRAM DESIGN Create a class named bankAccount. A bank account should have the following attributes: accNumber, balance, and dateOpened. This class should also have the option to do the following transactions: deposit, withdraw and drop. Initially there is only one bankAccount active in the program, with a balance amount of 1515, and was opened back in 10/01/1987. Depositing adds to a current bankAccount’s balance, while withdrawing – does otherwise. Dropping would equate the current balance to zero. Refer to the following class diagram for more details about the current bankAccount: bankAccountaccNumber = 1balance = 1515dateOpened = "10/27/1987" deposit(dep)withdraw(wd)drop(accNumber) INPUTThe input would be a string that contains the following data: the transaction to be done (dep – for deposit, wd – for withdraw and drop – for drop), the accNumber, and…arrow_forwardNutritional 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:…arrow_forward
