comparing string in file

Seraphimsan (954)
Well forgive me for the possibly obvious question. It's been 3 years since i've progammed in c++ :P

Anyways I'm trying to compare a string from a file to a string inputed to from a user. If the string doesnt match to any of the file, i want it to write it to the file. The writing part is working, the comparing? not so much.... It's a basic log in prompt.
(and no the problem isnt in the header)
...two of those headers I included from habit...
heres the code

Id like to point out that I'm rather new to object oriented programming, I've only studied it a little and that was 3 years ago....

what kind of file is this and what kind of matching you want to do? is it a whole line matching or word matching in file??
can you give an example for this?

while its an INI right now, though I havent formatted in the input like it is.
and it is whole line matching. Although I now know how to make it word matching

For an example?

Say Your a new user? Type in your name, I dont know, Alex? If that name is in the file, I want it to go to the return user function and execute that code, if not, I want it to create a new user.

does that help?
