«
»

This is a C# Program to find sum of the elements of each row of the given matrix.

Problem Description

This C# Program Finds Sum of the Elements of each Row of the Given Matrix.

Problem Solution

Here the sum of each row of the matrix is obtained by adding the elemnts of that corresponding row.

Program/Source Code

Here is source code of the C# Program to Find Sum of the Elements of each Row of the Given Matrix. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

for (j = 1; j <= n; j++)
{
r = r + a[i, j];
}
Console.WriteLine("{0} Row Sum : {1}", i, r);
}
}

{
mat ma = new mat();
ma.getmatrix();
ma.row();
}
}
}```
Program Explanation

In this C# program, we are creating an object variable ‘ma’ to the mat class. The getmatrix() method is used to find sum of the elements of each row of the given matrix. We are reading the number of rows and columns of the matrix using ‘m’ and ‘n’ variables respectively.

Using for loop we are entering the coefficient element values for the array variable a[i,j]. Using for loop in row() method, compute the sum of the elements of each column. Print the sum of the elements of each row of the matrix.

Runtime Test Cases
```
Enter the Number of Rows : 2
Enter the Number of Columns : 2
Enter the Elements :
1
2
3
4
Given Matrix :
1      2
3      4
1 Row Sum : 3
2 Row Sum : 7```
