Question
For your program you will create a class that represents a room. I have provided a main function (house.cpp) that tests the class that you will write. I have also provided a header file with the class declaration: Room.h. Your task is follow the comments in this file and implement the class (that is, write the definitions of the class member functions), as well as initializing the static data members. You also need to follow the comments in house.cpp to make the specified changes to this file.
When you run the main function I provided in house.cpp without the specified changes your output should look like the picture below. To see what your output should look like after the changes run my sample solution please.
