Write a program in C89 that takes in a TEXT FILE as input in

Write a program in C89 that takes in a TEXT FILE as input in via a command line argument. Output a bag of words of the words in the text file. Output this to bagofwords.txt. Look here for an understanding: https://en.wikipedia.org/wiki/Bag-of-words_model

Design the program to include encapsulating functionality and logical organization of functionality.

Bag of Words Output File
