This program illustrates the member function flip()
of the specialized container type vector<bool>.
Press Enter to continue ...

For a vector<bool> object of size 5 we have:
Size = 5  Capacity = 32
Press Enter to continue ...

Contents of v displayed without the boolalpha manipulator:
0 0 0 0 0
Press Enter to continue ...

Contents of v displayed with the boolalpha manipulator:
false false false false false
Press Enter to continue ...

Now we "flip" all values in the vector object, using v.flip().
Press Enter to continue ...

Contents of v displayed with the boolalpha manipulator:
true true true true true
Press Enter to continue ...

Finally, we "flip" all values in even positions,
using v[i].flip() (not the member function, note).
Contents of v displayed with the boolalpha manipulator:
true false true false true
