C# Sharp Array: Exercise-6 with Solution

Write a program in C# Sharp to print all unique elements in an array.

Sample Solution:-

C# Sharp Code:

``````using System;
public class Exercise6
{
public static void Main()
{
int  n,ctr=0;
int[] arr1 = new int[100];
int i, j, k;

Console.Write("\n\nPrint all unique elements of an array:\n");
Console.Write("------------------------------------------\n");

Console.Write("Input the number of elements to be stored in the array :");

Console.Write("Input {0} elements in the array :\n",n);
for(i=0;i<n;i++)
{
Console.Write("element - {0} : ",i);
}

/*Checking duplicate elements in the array */
Console.Write("\nThe unique elements found in the array are : \n");
for(i=0; i<n; i++)
{
ctr=0;

/*Check duplicate bifore the current position and
increase counter by 1 if found.*/
for(j=0; j<i-1; j++)
{
/*Increment the counter when the seaarch value is duplicate.*/
if(arr1[i]==arr1[j])
{
ctr++;
}
}
/*Check duplicate after the current position and
increase counter by 1 if found.*/
for(k=i+1; k<n; k++)
{
/*Increment the counter when the seaarch value is duplicate.*/
if(arr1[i]==arr1[k])
{
ctr++;
}
}
/*Print the value of the current position of the array as unique value
when counter remain contains its initial value.*/
if(ctr==0)
{
Console.Write("{0} ",arr1[i]);
}
}
Console.Write("\n\n");
}
}
```
```

Sample Output:

```Print all unique elements of an array:
------------------------------------------
Input the number of elements to be stored in the array :2
Input 2 elements in the array :
element - 0 : 2
element - 1 : 4
The unique elements found in the array are :
2 4
```
