Problem--Looking for stuff in a file

For this project use the text file here as data. Each line is a record, organized as follows:

FirstName� LastName� StNum� StName� StType� Age� Pool?� Dog?

George���� Smith���� 20���� Random� Way���� 56�� y����� y

Read the attached data file into a string (consult my web pages as needed) and have your program perform the following tasks:

Find the name and age of the oldest person.

Find how many people own pools.

Find how many people own dogs.

Sort the list by last name (Look on the web to see how to do that)

Print the answers to each question.
