A C program needs to be run on ocelot to read a text file and print it to the display. It should optionally find the count of the number of words in the file, and/or find the number of occurrences of a substring. You must use getopt to parse the command line. There is no user input while this program is running.

Usage: mywords [-c] [-f substring] filename

The -c flag means to count the number of words in the file.

A word would be a series of characters separated by spaces or punctuation. A word could include a hyphen or a single apostrophe.

The -f option will find the number of occurrences of the given substring.

You may have any number of the flags included or none of them.

The order they should be run would be: -c first and -f second.

Code needs to be ran with:

./mywords -c f he testfile

A makefile needs to be created to compile the program to create executable mywords. An ascii file name testfile with the text: The boy is sitting right there.

Don't copy or paste any of the solutions in this site; they're talking about a different variant of this question. I need some help here. Thanks.
