## C# Sharp Array: Exercise-23 with Solution

Write a program in C# Sharp to find sum of right diagonals of a matrix.

Sample Solution:-

C# Sharp Code:

``````using System;
public class Exercise23
{
public static void Main()

{
int i,j,sum=0,n;
int[,] arr1 = new int[50,50];

Console.Write("\n\nFind sum of right diagonals of a matrix :\n");
Console.Write("---------------------------------------\n");

Console.Write("Input the size of the square matrix : ");
n=Convert.ToInt32(Console.ReadLine());
Console.Write("Input elements in the first matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
Console.Write("element - [{0}],[{1}] : ",i,j);
arr1[i,j]=Convert.ToInt32(Console.ReadLine());
if (i==j) sum= sum+arr1[i,j];
}
}

Console.Write("The matrix is :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n ;j++)
Console.Write("{0} ",arr1[i,j]);
Console.Write("\n");
}

Console.Write("Addition of the right Diagonal elements is :{0}\n",sum);
}
}
```
```

Sample Output:

```Find sum of right diagonals of a matrix :
---------------------------------------
Input the size of the square matrix : 3
Input elements in the first matrix :
element - [0],[0] : 1
element - [0],[1] : 2
element - [0],[2] : 3
element - [1],[0] : 4
element - [1],[1] : 5
element - [1],[2] : 6
element - [2],[0] : 7
element - [2],[1] : 8
element - [2],[2] : 9
The matrix is :
1 2 3
4 5 6
7 8 9
Addition of the right Diagonal elements is :15
```
