hello_world_io.cpp

The classic first application "Hello, World!" with xtd::io::file and xtd::io::path classes.

#include <xtd/io/file>
#include <xtd/io/path>
#include <xtd/console>

using namespace xtd;
using namespace xtd::io;

auto main(int argc, char* argv[])->int {
  auto file_name = path::combine(path::get_temp_path(), "hello_world.txt");
  
  file::write_all_text(file_name, "Hello, World!");
  console::write_line(file::read_all_text(file_name));
  
  file::remove(file_name);
}

// This code produces the following output:
//
// Hello, World!
