Question

Hi

 

Please help me that my program gives correct output .

 

My program :

 

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace part1

{

class AQ

{

static void Main()

{

int count; int z=0;

string s = "twinkle twinkle little star how i wonder what u star little ";

string[] arr = s.Split(' ');

int length = arr.Length - 1;

for (int i = 0; i < length; i++)

{

count = 0;

for (int j = 0; j < length; j++)

{

if (arr[i] == arr[j])

{

count += 1;

}

}

if (i > 0)

{

if (count > 1)

{

Console.WriteLine(" {0} - {1} ", arr[i], count);

}

}

Console.ReadKey();

}

}

}

 

I am getting output like :
