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

Answer 1

C++11/Linux version:

#include 

if (auto dir = opendir("some_dir/")) {
    while (auto f = readdir(dir)) {
        if (!f->d_name || f->d_name[0] == '.')
            continue; // Skip everything that starts with a dot

        printf("File: %s\n", f->d_name);
    }
    closedir(dir);
}
