NAME

std::experimental::filesystem::path::remove_filename - std::experimental::filesystem::path::remove_filename

// Run this code

#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;

std::cout << fs::path("/foo").remove_filename() << '\n'
<< fs::path("/").remove_filename() << '\n';
}
