One choice is to implement this application efficiently by sorting all the words that occur in the text and then passing through the sorted sequence to identify one instance of each distinct word. Pick an appropriate sorting technique to use. You may grab the code from any reputable source. I have some books in my office that may prove useful for C, C++ and possibly Java.

You may also choose to implement this application using an appropriate data structure.

Write a brief report stating why you picked the sorting routine or data structure that you did. Also, state any assumptions you made when writing the program (i.e.: what is a word?). Run your program on both of the following files:

A small text file
A large text file

Remember the Programming and Documentation Style requirements!
