c++ – trying to iterate through files in folder and getting a weird error
It’s possible that the error you’re seeing when trying to iterate through files in a folder using C++ is related to the specific method or library you’re using for the iteration.
One common method for iterating through files in a folder in C++ is to use the <dirent.h>
header file, which provides functions for working with directories and directory entries. Here’s an example program that uses this header file to print out the names of all files in a specified directory:
c#include <iostream> #include <dirent.h> int main() { DIR *dir; struct dirent *ent; const char *dir_path = "/path/to/directory"; dir = opendir(dir_path); if (dir != NULL) { while ((ent = readdir(dir)) != NULL) { std::cout << ent->d_name << std::endl; } closedir(dir); } else { std::cerr << "Could not open directory" << std::endl; return 1; } return 0; }
Make sure to replace /path/to/directory
with the actual path of the directory you want to iterate through. If you’re still encountering an error, please provide more information on the error message you’re seeing so we can assist you further.
