Nest your QueryResult class inside TextQuery and rerun the programs you wrote to use TextQuery in § 12.3.2 (p. 490).

§ 12.3.2 (p. 490)

Exercise 12.30

Define your own versions of the TextQuery and QueryResult classes and execute the runQueries function from § 12.3.1 (p. 486).

§ 12.3.1 (p. 486)

Exercise 12.27

The TextQuery and QueryResult classes use only capabilities that we have already covered. Without looking ahead, write your own versions of these classes.

Exercise 12.28

Write a program to implement text queries without defining classes to manage the data. Your program should take a file and interact with a user to query for words in that file. Use vector, map, and set containers to hold the data for the file and to generate the results for the queries.

Exercise 12.31

What difference(s) would it make if we used a vector instead of a set to hold the line numbers? Which approach is better? Why?
