Files within Folders, how do I access them?

[satchmo05]

OK, so I'm working on a project for my class, and I have a problem.
They ask us to keep data files within a folder. The user is supposed to input the folder name and then the program should find x amount of files and then extract the data from them. How do I do that? Thanks in advance!

Well, you can basically pass the path of the file to the fstream.

For example, instead of simply doing something like:
fstream file("myfile.txt");

You can do something like:
fstream file("C:\mystuff\myfile.txt");

Although...I don't think there is a simple way to "scan" a directory and get the filenames out of it...try searching the forum, I think it has been asked before.

to find files in a directory use opendir, readdir and closedir function (on linux, unix)

to find files on windows use FindFirstFile, FindNextFile() class of functions.

these functions will open a directory for you and return each file/folder in that directory one by one. then you can open these file and can read data.
