Question

Create a class named RealEstate that has data members to hold the price of a house, the
number of bedrooms, and the number of baths. Member functions include overloaded
insertion and extraction operators. Write a main()function that instantiates a RealEstate
object, allows the user to enter data, and displays the data members entered. The main()
function should display an appropriate thrown error message if non-numeric or negative
values are entered for any of the data members. Save the file as RealEstate.cpp.
