No output! Parsing help? (Beginner)

[andimiami]

I need to take an input file that contains name listed like:
John Henry
Mary Baker
and create an output that looks like:
Baker, Mary.
Henry, John.
Right now my output is just
,.
,.
,.
,.
,.
,.
I can't use any global accesses, or a character processing alogorithm. I need to parse the line into a last name and a first name and then concatenate them so they look like the above example. This is my attempt, but I am really lost in my stringParseInput (string) algorithm. I am only getting
,.
,.
,.
,.
,.
,.
,.
Thanks for the advice!

string parseInputString (string)
       {
       string oneline;   
       string last, first, result;   
       oneline = last + ", " + first + ".";
       return oneline;           
       }

This function will always return ", ." because you never put anything in oneline, last, first or result. Also, whatever variable you're feeding to this function has no name, so you can't use it even if you wanted to.

Thanks for helping me out! Okay, so I did these changes. But I still get the same result. Am I still just way off? I feel so dumb right now! =C

Your function parseInputString build a string out of last and first.

last and first are empty in that function. You create them on line 88 and never put any values in them.
