Hi I was never taught this, but is it possible to create a txt file on notepad for example and then use fstream to read it into a program? I do not want any code, just a link would be good to a tutorial. None of my books state this, they all go on about writng data too a file, which I already know how to do.
Many thanks in advance. If it is not possible, please let me know also.

Check tutorials on file fstream, swgh. Particularly ifstream or Input/Output tutorials for a rundown on how to use both.
Edit: err... don't you usually answer other posters on fstream anyway?

Definitely possible, it is what I do for a "poor man's" graphical user interface sometimes.

As long as the file's been saved, then yes. It's the same as any other inreading(?).

I think you meant outreading.
I'm not sure. I think he wanted to input the file.
True, but I had a programmers block really cant remember how to do it. Anyways thanks guys for the replys. I'l check the online tutorials for a refresher. I wonder why none of my books could help me on this?Edit: err... don't you usually answer other posters on fstream anyway?

They probably do help you, you just never made the connection that all you are doing with an fstream is inputting and outputting text. Just pretend that whatever you typed into notepad was actually entered into the console and you were reading in with cin. It is the same idea.
In fact, you say you're used to using fstream's with data, but if you outputted your data to a file with a .txt extension, you can open it up in Notepad and look at it as well.
Unless you are doing binary output (and actually even then), whatever you write out from an ofstream can be read in Notepad, and whatever you type in Notepad can be read in with an ifstream.
Thanks daved. I must of overlooked what I was reading, I got it working now. Il have a good re-read over ifstream and make sure it all clicks. It never hurts to brush up.

I'd like to thank God, for making noodlebrains.
