I would separate out the setting of 'i' before the 'if', rather than
embedding the assignment in the call.

Also, I'm assuming that you'll need to call getline() for every line in
the file?  In which case, it will need to be in a loop.  (It looks like
getline() returns false upon end-of-file.)

I think what you're doing is the right approach.  Just need to go further.
