Example Detailed Explanation:
This program demonstrates the implementation of a communication interface and protocol for a labyrinth game. The code follows best practices in C++ and shows the interactions between the communication interfaces and the labyrinth protocol.
The program starts by defining a CommunicationInterface class with pure virtual functions for sending and receiving messages. This acts as a base class for specific communication interfaces.
Next, a Protocol class is created with pure virtual functions for connecting, disconnecting, sending packets, and receiving packets. This serves as a base class for specific protocol implementations.
The LabyrinthProtocol class is then defined, which inherits from the Protocol class. It provides the implementation for the Labyrinth protocol, including connecting, disconnecting, sending packets, and receiving packets. It also holds a pointer to a CommunicationInterface object to handle the actual communication.
Two communication interface implementations are provided: SerialCommunication and TCPCommunication. These classes implement the sendMessage and receiveMessage functions of the CommunicationInterface class with specific logic for serial and TCP/IP communication, respectively.
In the main function, two instances of the communication interfaces (SerialCommunication and TCPCommunication) are created. Then, the LabyrinthProtocol is tested with both communication interfaces. The protocol is connected to the communication interface, a packet is sent, received, and then the protocol is disconnected.
The output shows the connection status, messages sent and received, and the received packets for each test case using the LabyrinthProtocol with different communication interfaces.
Overall, this program demonstrates the use of communication interfaces and protocols in C++ for embedded systems, providing a flexible and extensible architecture for handling different communication methods in a labyrinth game.
