C++17 now has a std::filesystem::directory_iterator, which can be used as

#include 
#include 
#include 
namespace fs = std::filesystem;

int main() {
    std::string path = "/path/to/directory";
    for (const auto & entry : fs::directory_iterator(path))
        std::cout << entry.path() << std::endl;
}

Also, std::filesystem::recursive_directory_iterator can iterate the subdirectories as well.
