- Research assistants provide support to professionals who are conducting experiments or gathering andanalyzing information and data. Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.C++(OOP)Write a program that implements the following situation.A marketing organization ABC Ltd helps to promote the sales of other brands and products. ABCLtd has permanent employees and also hires employees from outside as well for different occasionson contract basis. A permanent employee gets monthly salary whereas contractual employee getspaid on daily wage rate along with basic salary.You need to create a class Employee with following data members.• String name• Int age• Int contact• Int CNIC• String educationYou will inherit the Employee class into Permanent_EMP and Contractual_EMP classes.In Permanent_EMP you are required to create following data members• Int basic_salary• Int allowancesIn addition, you are required to write down following class functions• A constructor that takes values of salary & allowances at the time of object declaration.• A method that calculates and returns the salary with following formulao Salary = basic_salary + allowances.In Contractual_EMP…Question 5Write a C++ program, you will create a class called Books to hold the information about the books in a library.

Implement the following getBookInfo () member function that receives a pointer to a book and fills it up with user data. User input validation is necessary. The user should be properly prompted for each field. void getBookInfo (Books *b) b. Implement the following printBookInfo () member function. void printBookInfo (Books *b) Your function should print the book in the following format: Book Title : Object Oriented Programming Using C++Author : Chris M. SzalwinskiPublisher : AmazonYear : 2016Subject : Computer ScienceBook Id : 00034 Note: You need to add required constructors/destructors, member functions or data members/variables in your program to complete its execution.
- C++ please! Create a class called Employee that includes three data members: a firstname (type string), a last name (type string), and monthly salary (type int).The class will have a constructor that initializes the three data members.Include the set and get member functions for each data member. If the monthlysalary is not positive, the set function will set it to 0. Also include amember function that returns the yearly salary (i.e. twelve times the monthlysalary).Write a test program that prompts the user to enter the first and lastname of an employee as well as their monthly salary. The program will thenoutput the yearly salary of the employee, give them a 10 percent raise, andoutput the yearly salary again.PLEASE HELP: In c++ please The class function needs to be in a header file (.h) The main needs to be on the main .cpp file. Please try to avoid using -> operators. Looking for a solution without them. Any help is very much appreciated. Much thanks! Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the…oop using c++ please give me full answer thanks Write a Program that implements Base class calculator and a Derived class scientific calculator, The Derived class should take the basic operations i.e. add, divide, subtract from calculator. However it should have its own methods such as square root.
- C++ PROGRAMS: Question#1:Define a class for rectangle objects defined by two points, the top-left and bottom-right corners of the rectangle. Include a constructor to copy a rectangle, a method to return a rectangle object that encloses the current object and the rectangle passed as an argument, and a method to display the defining points of a rectangle. Test the class by creating four rectangles and combining these cumulatively to end up with a rectangle enclosing them all. Output the defining points of all the rectangles you create.Question#2:Define a class, mcmLength, to represent a length measured in meters, centimeters, and millimeters, each stored as integers. Include methods to add and subtract objects, to multiply and divide an object by an integer value, to calculate an area resulting from the product of two objects, and to compare objects. Include constructors that accept three arguments—meters, centimeters, and millimeters; one integer argument in millimeters; one double…C++ Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following: Store the number as a Roman numeral. Convert and store the number as a positive integer. Print the number as a Roman numeral or positive integer as requested by the user. The integer values of the Roman numerals are: M 1000D 500C 100L 50X 10V 5I 1 Test your program using the following Roman numerals: MCXIV, CCCLIX, and MDCLXVI.c++ Friend function concepts Do not use operator overloading Write a Program to design a class complex to represent complex numbers and an input method "void input(float X, float Y)" for setting the values of complex number. Class should use an external friend function "friend complex sum (complex, complex);" to add two complex numbers and should return an object of type complex representing the sum of two complex numbers. Write another method "void show (complex c)" to show the final summation.
- C++ simple friend function. Create a C++ class called cube that calculates the volume of a cube. Use appropriate accessors (getters) and mutators (setters), constructors, etc. Your program must also include a friend function that will sum the volume of two cube class instances. Output the individual volumes of each of the two cube classes and then the total volume from the friend function.Write in C++ Language (Happy Coding):Create a class named 'Programming'. While creating an object of the class, if nothing is passed to it, then the message "I love programming languages" should be printed. If some String is passed to it, then in place of "programming languages" the name of that String variable should be printed.For example, while creating the object if we pass "cpp", then "I love cpp" should be printed.C++ A college must track equipment items purchased using special funds.Create an inventory class that represents an equipment item. An equipment item consists of an 8-alphanumeric inventory number, a short description of the item, the purchase price of the item, and its currentlocation (e.g.: room/building location). If an item is surplussed (e.g., gotten rid of), then the current locationshould say surplus, but the item should remain on the list.Write a program that reads inventory items from a file into a vector. Implement a menu system that allows theuser to add, edit, and delete records from the list as well as search the list based on inventory number and printa report of all records. The list should always be maintained in order of inventory number. When the programcloses, the data file should be overwritten with the most recent data from the list.
