// based on ex15.35

// Use diff tools to see the changes between this exercise and ex15.35. From
// the comparison, we should notice that just as user code is simplified by
// using the interface class, our own class code is also simplified by using
// the same interface class (at the cost of more function calls).

// Compile with parameter `/DDEBUG_LEVEL=1`(for Visual Studio) to enable print
// for ex15.36.
