How does your code get the word(s) to search for? Is there only one word, or are there more than one?
That could make a big difference in how you design your code.
Also, what do you know about the file before you start processing it? The more data you have, the better you can make your program perform. Because for a large file, scalability is going to be a problem.
Assuming you get the words to be searched via command line arguments, something like this could search a single line:
That should work to count words in a single line of text.
One thing that's important: having a maximum line length per file. Is that specified? If so, you can use "fgets()" and read one line at a time very simply:
