create an array of strings that hold filenames

[finkus]

Given a string that holds a the path to a directory, is there a way to create an array of strings (or char* or whatever) where each slot in the array holds the name of a file in that directory? I've actually done this in Perl, which is incredibly simple, but I have no experience with dealing with files in this way with C++. Any help would be greatly appreciated.

std::vector<std::string> filename;

ok... i guess i didn't quite phrase my question right. i dont know how to go about getting each filename to then store into the vector, if all i have is the directory name.

That's okay, I type slow. This is based on what is in the FAQ.

//
// Base: http://faq.cprogramming.com/cgi-bin/...&id=1044780608
//
#include <iostream> 
#include <string> 
#include <vector> 
#include <algorithm> 
#include <iterator> 
#include <dirent.h> 

int main(void)
{
   std::vector<std::string> filename;
   DIR *d = opendir(".");
   if ( d )
   {
      struct dirent *dir;
      // Load vector with filenames.
      while ( (dir = readdir(d)) != NULL )
      {
         filename.push_back(dir->d_name);
      }
      closedir(d);
   }
   // Show contents of vector.
   std::copy(filename.begin(), filename.end(),
             std::ostream_iterator<std::string> (std::cout, "\n"));
   return 0;
}

If it doesn't work for you, you may want to visit the FAQ to find one that is more likely to work.

EDIT: Sinkula's method is also very good and probably more portable.

ah... right, the FAQ. i probably should've looked there first, huh? anyway, thanks for the help Dave_Sinkula. i'll check that out now.

haha... thanks SlyMaelstrom... it's a much overdue introduction.

Ah yeah, I see from your other posts you've met.
