# C# Sharp Exercises: Find the sum of rows an columns of a Matrix

## C# Sharp Array: Exercise-25 with Solution

Write a program in C# Sharp to find the sum of rows an columns of a Matrix.

Sample Solution:-

C# Sharp Code:

using System;
public class Exercise25
{
public static void Main()
{
int i,j,n;
int[,] arr1 = new int[10,10];
int[] rsum = new int[10];
int[] csum = new int[10];

Console.Write("\n\nFind sum of row an column of a Matrix:\n ");
Console.Write("-------------------------------------------\n");

Console.Write("Input the size of the square matrix : ");

Console.Write("Input elements in the matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
Console.Write("element - [{0}],[{1}] : ",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");
}

/* Sum of rows */
for(i=0;i<n;i++)
{
rsum[i]=0;
for(j=0;j<n;j++)
rsum[i]=rsum[i]+arr1[i,j];
}

/* Sum of Column */
for(i=0;i<n;i++)
{
csum[i]=0;
for(j=0;j<n;j++)
csum[i]=csum[i]+arr1[j,i];
}

Console.Write("The sum or rows and columns of the matrix is :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
Console.Write("{0}    ",arr1[i,j]);
Console.Write("{0}    ",rsum[i]);
Console.Write("\n");
}
Console.Write("\n");
for(j=0;j<n;j++)
{
Console.Write("{0}   ",csum[j]);
}
Console.Write("\n\n");
}
}

Sample Output:

Find sum of row an column of a Matrix:
-------------------------------------------
Input the size of the square matrix : 2
Input elements in the matrix :
element - [0],[0] : 2
element - [0],[1] : 4
element - [1],[0] : 6
element - [1],[1] : 8
The matrix is :
2  4
6  8
The sum or rows and columns of the matrix is :
2    4    6
6    8    14

8   12
