-// Until now, we've only been printing our output in the console,
-// which is good enough for fighting aliens and hermit bookkeeping.
-//
-// However, many other tasks require some interaction with the file system,
-// which is the underlying structure for organizing files on your computer.
-//
-// The file system provides a hierarchical structure for storing files
-// by organizing them into directories, which hold files and other directories,
-// thus creating a tree structure that can be navigated.
-//
-// Fortunately, the Zig Standard Library provides a simple API for interacting
-// with the file system, see the detail documentation here:
-//
-// https://ziglang.org/documentation/master/std/#std.Io
-//
-// In this exercise, we'll try to:
-//   - create a new directory,
-//   - open a file in the directory,
-//   - write to the file.
-//
-// Note: For simplicity, we write byte-by-byte without buffering.
-// In real applications, you'd typically use a buffer for better
-// performance. We'll learn about buffered I/O in a later exercise.
-//

-    // it is a good habit to close a file after you are done with it
-    // so that other programs can read it and prevent data corruption
-    // but here we are not yet done writing to the file
-    // if only there were a keyword in Zig that
-    // allowed you to "defer" code execution to the end of the scope...

-}
-// to check if you actually write to the file, you can either,
-// 1. open the file in your text editor, or
-// 2. print the content of the file in the console with one of these commands
-//    Linux/macOS:   >> cat ./output/zigling.txt
-//    Windows (CMD): >> type .\output\zigling.txt

-// notice in:
-// ... try output_dir.createFile(io, "zigling.txt", .{});
-//                                                  ^^^
-//                 we passed this anonymous struct to the function call
-//
-// this is the struct `CreateFlag` with default fields
-// {
-//      read: bool = false,
-//      truncate: bool = true,
-//      exclusive: bool = false,
-//      lock: Lock = .none,
-//      lock_nonblocking: bool = false,
-//      mode: Mode = default_mode
-// }
-//
-// Question:
-//   - what should you do if you want to also read the file after opening it?
-//   - go to the documentation of the struct `std.Io.Dir` here:
-//     https://ziglang.org/documentation/master/std/#std.Io.Dir
-//       - can you find a function for opening a file? how about deleting a file?
-//       - what kind of options can you use with those functions?
