I take it this is a console application that you are writing - there are utilities to do this very same thing, so I must assume this is a homework assignment....

Can you post what code you have so far and then we can help you move it along????

Since ANSI C++ does not support this type of functionality, you have to use OS specific code.

What is your OS, and compiler?

For Windows and DOS, use the findfirst and findnext functions.

For Unix opendir and readdir functions

Agree with Axter. Post information about OS and Compiler.

opendir and readdir should work on most Unixes as well as Dos/Windows when using Borland C or GCC.

I didn't know that.  I can see why GCC would support opendir, but I wonder why Borland C supports it.

Do they also support findfirst?

Might be too harsh, I came here because I need to do this also - but not for homework, if only I *was* a student again :-)

Dunno either, but they do, at least Borland mentions them (directory streams) in the help files :)

Maybe it's homework, maybe he just wants a nice tool to find a file once in a while. I've been contemplating an easier version of change-dir (their used to be a dos tool like it)

I created wrapper functions to allow findfirst/findnext to work with compilers that only support opendir/readdir.

I did that so I didn't have to change my code when I port it to unix.  But I guess now I could use it if I ever need to port it to Borland C or GCC.
