I am writing a program in C++ that needs access to files to determine and store user options, write now the program uses a separate file for each option rolleyes.gif
What I want to do is store the option data in one file, keep each line of the file for a different option then have the program read the file and store each line as a separate variable.
-Thanks

Then I recommend you go with an INI file format which lends itself to program configuration settings. The way this is structured will allow you to not only look up sequentially but also jump to specific sections like an index if the need ever arises.

You can check out the wikipedia article on this file type to get an idea how it might work for you.

I recommend .csv extension file. You can I/O variable in separate line.
Easy to modify and very light

Ok, I looked at the article at wikipedia, but how do you work with .INI files in C++?

There are only two types of files as far as C++ is concerned - Binary files, where you read a byte at a time, and build objects from the ground up,
or text files, where you read a line or character at a time, and parse strings for tokens & symbols.

How you do anything with the data after that (text files are far easier), is up to you. The easiest way is to set up some simple rules about what format the data will be stored in, and tokenise the input from there.

It's called "Data Parsing".
