How do I swap the pointers as described in this paragraph?
Space saving isn’t the only advantage that you get by using pointers. In a lot of circumstances you save
time, too. Think of what happens if you want to move "Oliver Hardy" to the fi rst position and "Robert
Redford" to the end. With the pointer array as in Ex4_07.cpp, you just need to swap the pointers — the
strings themselves stay where they are.
