Question Create a class called Quadratic for performing arithmetic on and solving quadratic equations. A quadratic equation is an equation of the form ax2 + bx + c = 0 Where a !=0. Use double variables to represent the values of a, b, and c and provide a constructor that enables objects of this class to be initialized when they are created. Give default values of a = 1, b = 0, and c = 0. Create a char variable called variable to represent the variable used in the equation and give it a default value of x. The constructor should not allow the value of a to be 0. If 0 is given, assign 1 to a). Provide public member functions that perform the following tasks. add—adds two Quadratic equations by adding the corresponding values of a, b, and c. The function takes another object of type Quadratic as its parameter and adds it to the calling object. subtract—subtracts two Quadratic equations by subtracting corresponding values of a, b, and…
Create a class called Employee that includes three pieces of information as data members—a first name (type string), a last name (type string) and a monthly salary (type int). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10 percent raise and display each Employee’s yearly salary again.
C- Create the sub class UsedBook that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int) // how old the book is in years Constructor that takes all of the above variables as input parameters. set/get functions calculate_price method // the price is calculated as price_new * (1- 0.10*age) print function that prints all information related to the old book. D- Create the Testing class that has the main method and does the following: aa- Use the constructor to create instance of NewBook class and name it as new. Call compute_price function. bb- Use the constructor to create instance of usedBook class and name it used. Call compute_price function. cc- Print the related information of new and used objects using print functions. Use this following code: 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…

Assume that the following is a constructor, which appears in a class:ClassAct(int number){item = number;}a) What is the name of the class that this constructor appears in?b) Write a statement that creates an object from the class and passes the value 25 as an argument to the constructor.
C++ Dont include new files. READ ME PetsBreed ClassCreate a Breed class with the following: Member VariablesCreate the following private member variables, all of type std::string: species_breed_name_color_ConstructorsCreate a default constructor for Breed that sets its species_ to "Dog", breed_name_ to "Pug", and color_ to "Fawn".Create a non-default constructor that receives a std::string for species_, breed_name_, and color_; in that order. The values from the constructor should appropriately assign the member variables.Accessors and MutatorsCreate accessors and mutators for all member variables, following the naming conventions covered in class. e.g. for species_, name the accessor Species, and the mutator SetSpecies.

Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at store. An Invoice should include six data members- a) part number (type string) b) part description (type string) c) quantity of the item being purchased (type int) d) price per item (type int) e) value-added tax (VAT) rate as a decimal (type double) f) Discount rate as a decimal (type double). Your class should have a constructor that initializes the six data members. The constructor should initialize the first four data members with values from parameters and the last two data members to default values of 0.20 per cent and zero respectively. Provide a set and a get functions for each data member. In addition, provide a member function named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item and applies the tax and discount amounts), then returns the amount. Have the set data members perform validity checks…
Create a class called time. The time class has three private data members of type int, named hours, minutes and seconds. • Provide a no‐argument constructor for the class which initializes the data members to 0. • Provide another constructor which sets the data members to the values passed from the main. It should also validate whether the values are correct i.e., hours should be between 0 and 23 (inclusive), minutes should be between 0 and 60 (inclusive) and seconds should also be between 0 and 60 (inclusive). If an invalid value is entered, the constructor should automatically change it to 0. • Write a function getTime() which asks the user to input the values for hours, minutes and seconds. While taking the input values, it must also validate the input values as in the above case. • Write a function displayTime() which displays the time in the format 11:39:45 i.e. hours:minutes:seconds. • Write a function totaltime () that adds two objects of type Time passed as…
Create a class named RealEstate that has data members to hold the price of a house, the number of bedrooms, and the number of baths. Make a member function get_Data() that gets the RealEstate's data from the user, and throws an appropriate error message if negative values are entered for any of the data members. Add a display() function that displays the RealEstate's data. Write a main() function that instantiates a RealEstate object, allows the user to enter the RealEstates data, use an ofstream object to store the RealEstate's data in RealEstate.dat file, and close the ofstream object. Then open an ifstream object to read information from file, RealEstate.dat, and displays the information.
Create a class called Employee that includes four pieces of information as data members — a first name (type string), a middle name (type string) , a last name (type string)and a monthly salary (type int). Your class should have a constructor that initializes the four data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary.
