This is a basic console-based chatbot that greets the user, echoes back whatever the user inputs, and exits when the user types "exit" or "bye". You can expand this by adding more complex logic to handle different types of user input and generate varied responses.
Compile this code using a C++ compiler (like g++ for Linux or MinGW for Windows) to create an executable. When run, it will prompt the user for input and respond accordingly.
Remember, this is a very simple example. For more sophisticated chatbots, you'd typically incorporate natural language processing
