This was one of my early C++ programs I have written. The goal was to implement a balance binary tree structure (Red Black tree) and demonstrated it. This program when executed accepts an argument for specifying a filename for it to process. It will retrieve all the words in the file and adds them in the tree sorted. It will then provide results of all the words sorted and the number of occurrences and tree processing stats. The results will be stored in a file called results.out.

An example:

C:>wordtreestats input.txt
Results stored within result.out.

result.out:

List of sorted distinct words and their # of occurrences:
