1- Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as 3.14159 * radius * radius 2- Add a default constructor to the Circle class in question (1). The constructor should initialize the radius member to 0 3- Add an overloaded constructor to the Circle class in question (2). The constructor should accept an argument and assign its value to the radius member variable
Colorful bubbles In this problem, you will use the Bubble class to make images of colorful bubbles. You will use your knowledge of classes and objects to make an instance of the Bubble class (aka instantiate a Bubble), set its member variables, and use its member functions to draw a Bubble into an image. Every Bubble object has the following member variables: X coordinate Y coordinate Size (i.e. its radius) Color Complete main.cc Your task is to complete main.cc to build and draw Bubble objects based on user input. main.cc already does the work to draw the Bubble as an image saved in bubble.bmp. You should follow these steps: First, you will need to create a Bubble object from the Bubble class. Next, you must prompt the user to provide the following: an int for the X coordinate, an int for the Y coordinate, an int for the Bubble's size, and a std::string for the Bubble's color. Next, you must use the user's input to set the new Bubble object's x and y coordinates, the size, and the…

A class named CafeService contains • Two data members i.e. the orderID and the price of food item(s) served by • A no-argument constructor to initialize both data fields with default values of “ord#0”, 0.0• A parameterized constructor to initialize all data fields with user-defined valuesDerive a class named StaffService from the class CafeService that holds the following:• Two data members i.e. o serviceFee, o the cabinNumberto which the service has been made• A function named totalCharges that returns total cost of an order (including serviceFee + price of food item(s) served)• A parameterized constructor, which requires arguments for all of its own data fields as well as for the data fields of base class• A member function named display() to show all the details of an order including orderID,price, and totalChargesIn the main() function, instantiate an object of class StaffService object and test the implementation of both classes through this object.
In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

Write a class named as vehicle which has some attributes this class has three functions.i.e.fuelAmount ()loadingCapacity()applyBrakes()enginePower()Write a class named as Bus, Car and Truck which are inherited from class Vehicle. Also write the setter/getter, default and parameterized constructor in each class.

Create a class called Account that a bank might use to represent customers' bank accounts. Your class should include one data member as int accountNumber and other of type float to represent the account balance. Your class should provide a default and parameterized constructor that receives an initial balance and accountNumber and uses it to initialize the data members. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, the balance should be set to 0 and the constructor should display an error message, indicating that the initial balance was invalid. The class should provide getter/setters for data members. The class should provide three member functions. Member function credit (float amount, int accountNumber) should add an amount to the current balance. Member function debit (float amount, int accountNumber) should withdraw money from the Account and should ensure that the debit amount does not exceed the Account's…
