using System;

namespace Samples
{
  public class ConsoleSample
  {
    public static void Main()
    {
      Console.WriteLine("Write a string {0}",
                        "Hello world!");
      Console.WriteLine("Write a number {0}", 42);
      Console.WriteLine("Please enter your name:");   
      string name = Console.ReadLine();
      Console.WriteLine("Hello {0}", name);
      Console.Error.WriteLine("Errors go here by default");
      Console.WriteLine("Date: {0:dd/MM/yy}", DateTime.Now);
      int i = -42;
      Console.WriteLine("{0:0000}, {1, -20}, {2, 20}.", i, i, i);
      Console.WriteLine("{0:X}, {1:C}, {2:G}.", i, i, i);
    }
  }
}
