The function printNow is not the only way to present information to the user during the running of a program. We might also use the function showInformation which takes a string as input, then displays it in a dialog box. Currently, our showRoom subfunctions presume that we will display the room information via printNow. If functions like showPorch returned a string with the description, then the function showRoom could either use printNow to display the room description or showInformation. Rewrite the room showing functions to return a string, then modify showRoom to easily change between printing the room information and showing it in a dialog box.

Question

Note: As stated in the question, each of the show room functions has to be changed to return a string. In particular, in order to ensure that the text is still readable, the altered functions should make use of the new line character “\n”. Additionally, the easiest way to “choose” between two options is to make use of a Boolean to switch between printing and dialog boxes. There’s a number of different potential answers to this question, one approach (as below) is to just write a new function to handle text output, but one could also handle the switching entirely within showRoom.

Answer 1

```
