Write a program that starts with a base class employee. This class contains employee’s name and employee number. From this class inherit three other classes which are manager, scientist and laborer. The manager and scientist classes should contain additional information about these categories of employee and member functions.
Override the methodwhich calculate salary of employee in its each child class.
