Answer only one question: 1- Write a C+ class and choose any name for it. The class should have two private members and two public members. Write a constructor to initialize these members to zero. Write another constructor to initialize these members to non-zero values. Write a method to return the average of the class members. Write a C++ program and initialize the members of the class with [2,5,8,3] respectively and call its method to calculate the averuge. • You are allowed to use materials that is not covered in our lectures

in c++ A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.
In c++ ( without empty constructor)Create a lecturer class with member-data name (name) and department (department). For the Lecturer class, write constructors, get & set methods, and the toString () method, which returns the textual description of the object. Write a Lecture class with data member:- subject (discipline)- weekday (day of the week when it takes place)- hour (start time, integer)- online (boolean value, whether remote or not)- lecturer (object of class Lecturer)For the Lecture class, write:- constructors- get & set methods- method isItMorning (), returning a Boolean value, the result of checking whether the lecture starts at 7-11- give a new implementation of the toString () method so that it returns the text description of the Lecture objectIn the test function main ()1. Create objects of both classes and illustrate the use of all possible methods for them.2. Create an array of Lecture objects and display it on the screen and in a file.
In C++ Language: Suppose I have a class named Person. Here is how I would like to use the class: //Create a person named Dave Smith Person dave("Smith", "Dave", 'R'); //Create a person named Gal Gadot Person gal("Gadot", "Gal", 'G'); //Dave and Gal gets married gal = dave + gal; dave = dave + gal; //print Gal and Dave's new married name cout << gal << endl; cout << dave << endl; This will output the following: Gal Smith-Gadot Dave Smith-Gadot Write the class declaration for Person

Can I please get help writing this in c++ Create a base class called Animal. All animals have a name (i.e. “Fido,” “Thumper,” “Princess,” “Nemo,” etc.) and an age. Provide a default constructor that initializes the age to zero and outputs the message “Invoking the default Animal constructor” and another constructor that allows the name and age to be set by the client. This other constructor should also output the message “Invoking the 2-argument Animal constructor.” Also construct a destructor for this class that outputs the message “Invoking the default Animal destructor.” Your Animal class should have a function called Move that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the name and age to be accessed. From the Animal class, derive Dog, Rabbit, Fish, and Snake classes. The derived classes should each have constructors and destructors that output an appropriate message (e.g., the…
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.
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)
Employee Class (Medium) Write a class in C++ named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions…
C++ 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 color using…

Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…
