Write a class Employee with data members Name, Id, and Salary. Derive two classes, Faculty with data members Department, and role(permanent or visiting) and derived class Management with data members Department and rank (manager, deputymanager, etc.). Create getters,settersfor all thedata members, create constructors,destructors and show functions for all the classes.Create a write function to write employees on a file . In main function create two objects of each derived class using parameterized constructors, call the show function to show all four objects, write all four objects to a file. Your submission should include the output file.

The grades can be integers (0-100), doubles (0.0-100.00) and characters (A-F, where F denotes grades less than 50). Write a class template to accommodate all five types of grades. The class template must have two constructors (no-arg constructor, and aconstructor that takes 7 parameters: name, age and grades of 5 exams). Write a c++ function to read an object from console, and another function to print the object to the console. Implement the class template by creating three objects with three different types (int, double and char) of grades, and printing the objects on the console.arrow_forward7.23 LAB: Product class use Java.
