Oks na sana sa Exception Handling ang problema ko nlang sa printing. Dapat daw kc base sa input ng user yung pag print ng mga locations.

Paanong base lang sa input ng user.
Sample input output daw.

Aral ka ng mga loops. Pano kung 1,000,000 locations yan? 1,000,000 beses ka mag p-print?
Tinanggal ko na yung returnn list mo dahil hindi ko alam kung saan ginagamit yun.


static void Main(string[] args) { List<string> Locations = new List<string>(); Locations.Add("Manila"); Locations.Add("Batanes"); Locations.Add("Tagaytay"); Locations.Add("Baguio"); Locations.Add("Batangas"); Locations.Add("Cebu"); Locations.Add("Palawan"); Locations.Add("Davao"); Locations.Add("Puerto Galera"); Locations.Add("Bohol"); while (true) { Console.Write("How many locations would you like to see? "); int choice = Convert.ToInt32(Console.ReadLine()); for (int iterateLocations = 0; iterateLocations <= choice - 1; iterateLocations++) { Console.WriteLine(Locations[iterateLocations]); } Console.Write("\n\nWould you like to try again? [Y/N]: "); string tryAgain = Convert.ToString(Console.ReadLine()); if (tryAgain == "Y") { continue; } else if (tryAgain == "N") { break; } } Console.Read(); }

Salamat lods, tinignan tinignan ko kung paano yung looping convenient nga gamitin..
