1. Whovian's guess is correct.
2. All the background that I can possibly give you: I'm trying to solve http://projecteuler.net/problem=42. Please: no hints or give-aways on how to solve the problem. Just how to use words.txt.
I must improve on making my question clearer. I'm trying to words.txt in my C program. We #include libraries. But, obviously, #include <words.txt> doesn't work. Then, how do we use words.txt in the program? That's my question.
Sorry for the trouble and thanks for trying to help me out.
