// Quiz time. See if you can make this program work!
//
// Solve this any way you like, just be sure the output is:
//
//     my_num=42
//
const std = @import("std");

pub fn main() !void{
  var stdout = std.fs.File.stdout().writer(&.{});
  
  const my_num: u32 = getNumber() catch 42;
  
  try stdout.interface.print("my_num={}\n", .{my_num});

// This function is obviously weird and non-functional. But you will not be changing it for this quiz.
