# C# Sharp Exercises: Count frequency of each element of an array

## C# Sharp Array: Exercise-8 with Solution

Write a program in C# Sharp to count the frequency of each element of an array.

Sample Solution:-

C# Sharp Code:

``````using System;
public class Exercise8
{
public static void Main()
{
int[] arr1 = new int[100];
int[] fr1 = new int[100];
int n, i, j, ctr;

Console.Write("\n\nCount the frequency of each element of an array:\n");
Console.Write("----------------------------------------------------\n");

Console.Write("Input the number of elements to be stored in the array :");
n = Convert.ToInt32(Console.ReadLine());

Console.Write("Input {0} elements in the array :\n",n);
for(i=0;i<n;i++)
{
Console.Write("element - {0} : ",i);
arr1[i] = Convert.ToInt32(Console.ReadLine());
fr1[i] = -1;
}
for(i=0; i<n; i++)
{
ctr = 1;
for(j=i+1; j<n; j++)
{
if(arr1[i]==arr1[j])
{
ctr++;
fr1[j] = 0;
}
}

if(fr1[i]!=0)
{
fr1[i] = ctr;
}
}
Console.Write("\nThe frequency of all elements of the array : \n");
for(i=0; i<n; i++)
{
if(fr1[i]!=0)
{
Console.Write("{0} occurs {1} times\n", arr1[i], fr1[i]);
}
}
}
}
```
```

Sample Output:

```Count the frequency of each element of an array:
----------------------------------------------------
Input the number of elements to be stored in the array :3
Input 3 elements in the array :
element - 0 : 10
element - 1 : 15
element - 2 : 10
The frequency of all elements of the array :
10 occurs 2 times
15 occurs 1 times
```
