Add a menu option: Enter new Person. This will need to:

1. Get a new person from the keyboard.

2. Create a new array, 1 cell bigger than the current array (call it tempPeople).

3. Use ArrayCopy to copy the old data to the new array.

4. Add the new person to the end of the array.

5. Assign the new array to the old reference:

people = tempPeople.

6. Repeat for EmployeeProgram.

here is thr existing code.
