- Create an ObjectCounter class that allow a static data member to be updated when new object is created from the type ObjectCounter. In the main function create 3 objects and each time print the number of objects createdWrite 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.Using Java, create an ObjectCounter class that allow a static data member to be updated when new object is created from the type ObjectCounter. In the main function create 3 objects and each time print the number of objects created

It can be called to construct a new object, just like any other constructor. b. It is also called when a value parameter is an object. c. It is call when a function returns an object. d. It is call when an object is destroyed. Group of answer choices a, b, and c a, b, c, ad d b and c a only a and b
- Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.What purpose does a copy constructor serve? Under what circumstances is it required?
- Create a class for smart pointers. A smart pointer is a data type that simulates a pointer and offers automated garbage collection. It is often implemented using templates. When the number of references to a SmartPointerT*> object drops to zero, the object of type T is immediately released.C++ requires that a copy constructor's parameter be a class object passed by _________________.For this problem you need the Employee class again. Write another main function to answer the following questions. Only submit the main function for this problem. Create an Employee object using the constructor with parameters. Declare an Employee pointer and make it point to the Employee object created in part (i). Use the pointer to call the print() method of the object. Dynamically create an Employee object using the constructor with parameters and make the Employee pointer point to this newly created dynamic object. Use the pointer to set the name of the Employee to some other name. Use the pointer to call the print function. Use the pointer to allocate a dynamic array of three employees and populate the array with Employee objects. What happens to the previously allocated memory for the Employee in part (iv)? Use a for loop to print the Employees objects in the dynamic array constructed in part (vii). Delete the pointer and set it to point to NULL. Explain what does this step…
