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…
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.
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 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.
(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.

# Pets## Breed ClassCreate a `Breed` class with the following: ### Member VariablesCreate the following private member variables, all of type `std::string`: 1. `species_`2. `breed_name_`3. `color_` ### Constructors1. Create a default constructor for `Breed` that sets its `species_` to `"Dog"`, `breed_name_` to `"Chihuahua"`, and `color_` to `"Fawn"`.2. 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`. ## Pet ClassCreate a `Pet` class with the following: ### Member VariablesCreate the following private member variables:1. `std::string name_`2. `Breed breed_` 3. `double weight_` ### Constructors1.
