Write a C# Sharp program to use each of the standard date time format strings to display the string representation of a date and time for four different cultures

using System;
using System.Globalization;

public class Example39
{
   public static void Main()
   {
      // Create an array of all supported standard date and time format specifiers.
      string[] formats = {"d", "D", "f", "F", "g", "G", "m", "o", "r", 
                          "s", "t", "T", "u", "U", "Y"};
      // Create an array of four cultures.                                 
      CultureInfo[] cultures = {CultureInfo.CreateSpecificCulture("zh-HK"), 
                                CultureInfo.CreateSpecificCulture("en-US"),

      DateTime dateToDisplay = new DateTime(2015, 10, 16, 17, 4, 32);

      // Iterate each standard format specifier.
      foreach (string formatSpecifier in formats)
      {
         foreach (CultureInfo culture in cultures)
            Console.WriteLine("{0} Format Specifier {1, 10} Culture {2, 40}", 
                              formatSpecifier, culture.Name, 
                              dateToDisplay.ToString(formatSpecifier, culture));
