Question

The Doctor program described in Chapter 5 combines the data model of a doctor and the operations for handling user interaction. Restructure this program according to the model/view pattern so that these areas of responsibility are assigned to separate sets of classes.

The program should include a Doctor class with an interface that allows one to obtain a greeting, a signoff message, and a reply to a patient’s string.

To implement the greeting, define a method named greeting for the Doctor class. To implement the signoff message, define a method named farewell for the Doctor class. Both greeting and farewell should return a string with a greeting or farewell message respectively. The reply function is defined for you, it should be added as a method for the Doctor class.

The rest of the program, in a separate main program module, handles the user’s interactions with the Doctor object. Develop this program with a terminal-based user interface.

Note: The program should output in the following format:

Hello, how can I help you today?

> I am sick

You seem to think that you are sick?

> Yes

And what do you think about this?

> I am not feeling good

Did I just hear you say that you are not feeling good?

> Yes

Why do you believe that Yes?

> My nose is running I would like to hear more about that.

> I have a headache too

You seem to think that you have a headache too?

> Correct Go on.

> It doesn't stop

Did I just hear you say that It doesn't stop?

> Correct Go on.

> That's it

And what do you think about this? > quit Have a nice day!
