using System.Linq;
using System.Text;

namespace Indexer
{
class Tutorial
{
string [] name=new string[15];
public string this[int range]
{
set { name[range] = value; }
get { return name[range]; }
}
static void Main(string[] args)
{
Tutorial p = new Tutorial();
p[0] = "Mike";
p[1] = "Milan";
p[2] = "Vihar";
p[3] = "Vivek";
p[4] = "Sharad";
Console.Write(" {0} \n {1} \n {2} \n {3} \n {4}",p[0],p[1],p[2],p[3],p[4]);
