Dirent.h - get the strings for files with a certain extension exclusively

Having a few issues trying to think of a good way to have a directory traverser that will only select wav files and return the strings for those files exclusively, e.g. just wav files. I can stop dirent.h looking in subdirectories, I'm pretty sure I just need an if statement that only allows files with .wav in string So far my code looks like this, I just extended a few examples I've seen on the wiki page for the header file: ``` ifstream fin; string dir, filepath; DIR *dp; struct dirent *dirp; struct stat filestat; cout << "dir to get files of: " << flush; getline(cin, dir); dp = opendir( dir.c_str() ); if (dp == NULL){ cout << "Error(" << errno << ") opening " << dir << endl; } while ((dirp = readdir( dp ))){ filepath = dir + "/" + dirp->d_name; if (stat( filepath.c_str(), &filestat )) continue; if (S_ISDIR( filestat.st_mode )) continue; fin.open( filepath.c_str() ); stringVec.push_back(filepath); fin.close(); } closedir( dp ); for(int i=0;i<stringVec.size();i++){ cout << stringVec[i] << endl; } ``` Any help appreciated, I'm its not super difficult - but so far I haven't been able to figure it out.
