Write a C program to 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.

• o mywords -c -f he testfile

• Create a simple Makefile to compile your program into an executable called mywords.

  • Create an ASCII file named testfile with the text: The boy is sitting right there.

  • Test the program with the following commands:
