How can I get the list of files in a directory using C or C++? -

how can determine list of files in directory inside c or c++ code?

i'm not allowed execute 'ls' command , parse results within program.

in small , simple tasks not use boost, use dirent.h available windows:

dir *dir; struct dirent *ent; if ((dir = opendir ("c:\\src\\")) != null) {   /* print files , directories within directory */   while ((ent = readdir (dir)) != null) {     printf ("%s\n", ent->d_name);   }   closedir (dir); } else {   /* not open directory */   perror ("");   return exit_failure; } 

it small header file , of simple stuff need without using big template-based approach boost(no offence, boost!). googled , found links here author of windows compatibility layer toni ronkko. in unix standard-header.

update 2017:

in c++17 there official way list files of file system: std::filesystem. there excellent answer shreevardhan below source code:

#include <string> #include <iostream> #include <filesystem> namespace fs = std::filesystem;  int main() {     std::string path = "path_to_directory";     (auto & p : fs::directory_iterator(path))         std::cout << p << std::endl; } 

consider upvoting answer, if using c++17 approach.
