Eternal data files

[lovely6922]

I need to figure out how to compare a variable enter by the user to data that is stored in an external data file. Any suggestions?

Looking for something a bit less generalized. I am not familiar with strings as they haven't been covered in my class yet. All we have been taught is the code for the string compare function and what a literal string is. Which if I understand it right, I am using a literal string for my external data file name. I just need to see an example of how to compare a user entered variable name to the data in a file looking for a match. Any more suggestions?

The first 3 links will help you with that...or are you using C?
