Design pattern C + + implementation 13: Adapter mode

Adapter mode (Adapter): Transforms the interface of one class into another interface that the customer wants. Make the original interface incompatible and not work in one of those classes that can work together.

Usage Scenario: When the data and behavior of the system are correct, but the interface is not the same, we can consider using the adapter mode to match the interface. The main application is in the hope of reusing some existing classes, but the interface and multiplexing environment should not be used at the same time.
