## C# Sharp Array: Exercise-16 with Solution

Write a program in C# Sharp to find the second largest element in an array.

Sample Solution:-

C# Sharp Code:

``````using System;
public class Exercise16
{
public static void Main()
{
int n,i,j=0,lrg,lrg2nd;
int[] arr1 = new int[50];

Console.Write("\n\nFind the second largest element in an array :\n");
Console.Write("-----------------------------------------\n");

Console.Write("Input the size of array : ");
/* Stored values into the array*/
Console.Write("Input {0} elements in the array :\n",n);
for(i=0;i<n;i++)
{
Console.Write("element - {0} : ",i);
}
/* find location of the largest element in the array */
lrg=0;

for(i=0;i<n;i++)
{
if(lrg<arr1[i])
{
lrg=arr1[i];
j = i;
}
}
/* ignore the largest element and find the 2nd largest element in the array */
lrg2nd=0;
for(i=0;i<n;i++)
{
if(i==j)
{
i++;  /* ignoring the largest element */
i--;
}
else
{
if(lrg2nd<arr1[i])
{
lrg2nd=arr1[i];
}
}
}

Console.Write("The Second largest element in the array is :  {0} \n\n", lrg2nd);
}
}
```
```

Sample Output:

```Find the second largest element in an array :
-----------------------------------------
Input the size of array : 5
Input 5 elements in the array :
element - 0 : 2
element - 1 : 4
element - 2 : 6
element - 3 : 8
element - 4 : 10
The Second largest element in the array is :  8
```
