For my next assignment we are learning how to incude different files in our directories. My professor gave us one example file and said to modify it where need be. When I download the file off of the website it is in the form of "file". I'm thinking I need to get this in the form of .C or something so I can read the code inside. Not very good with gcc thoroughly.

So my question is how do I change this file to where I can read what is inside it? Thanks
