"In the student sample program files for this chapter, you will find a text file named house_prices.csv. The file contains the following data about houses for sale in a city:
Price
Number of bedrooms
Number of bathrooms
Square feet of living space
The data stored in each line is formatted in the following way:
Price,Bedrooms,Bathrooms,SquareFeet
Notice that the data items are separated by commas. The first line in the file looks like this:
221900,3,1,1180
The data stored in this line is:
Price = $221,900
Bedrooms = 3
Bathrooms = 1
Square feet = 1,180
Design a class that has properties for the four pieces of data. In an application, read the file and store each house’s data in an instance of the class. The class instances should be stored in a List.
The application should let the user search the List for the prices of houses with the number of bedrooms within a range, the number of bathrooms within a range, and the square feet of living space within a range. For…
