Write a program in C that will output the unique words in a file along with the number of times the word appears. Must be done using a binary search tree. The file will be written in sentence form and punctuation must be handled as well. For example, if the file reads:

"I really love apples, they are the best. I want some of Chris' apples and some of John's apples as well. Can I have some?"

and would output each unique word in alphabetical order along with how many times it apears.

For example:

apples, 3

etc.
