How do I get a list of files in a directory in C++?

Question

How do you get a list of files within a directory so each can be processed?

Answer 1

You have to use operating system calls (e.g. the Win32 API) or a wrapper around them. I tend to use Boost.Filesystem as it is superior interface compared to the mess that is the Win32 API (as well as being cross platform).

If you are looking to use the Win32 API, Microsoft has a list of functions and examples on msdn.
