please help me complete the following code using C++

• Implement a simple inheritance hierarchy between the Person and Employee classes, where both classes include a pointer-based dynamic array. As a result, you are required to include the big-3 in both classes.
• Implement a set of virtual functions to realize polymorphism.
• Take advantage of polymorphism to manage a dynamic array that consists of both Person objects and Employee projects.
