Write a program in C89 that takes in a TEXT FILE as input in via a command line

Question

Write a program in C89 that takes in a TEXT FILE as input in via a command line argument. The program should print to the screen the number of characters in that file, the number of words in that file (a word is any sequence of non-white-space characters), and the number of lines in that file.

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

Additional: 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 (Links to an external site.)

Standard Input/Output Example

./a.out sometextfile.txt
Number of Characters: 65
Number of Words: 18
Number of Lines: 3

Bag of Words Output File

John: 1
likes: 2
to: 3
watch: 4
movies: 5
also: 6
football: 7
games: 8
Mary: 9
too: 10
