{
public static void Main()
{
List<string> letters = new List<string>();
Console.WriteLine("\nCapacity: {0}", letters.Capacity);
letters.Add("A");
letters.Add("B");
letters.Add("C");
letters.Add("D");
letters.Add("E");
Console.WriteLine("Capacity: {0}", letters.Capacity);
Console.WriteLine("Count: {0}", letters.Count);
