Sum of rows of MATRIX elements

Here, we will read a 2X3 matrix from the user then calculate the sum of rows elements and then print the sum on the console screen.

Program/Source Code:

The source code to calculate the sum of rows of MATRIX elements is given below. The given program is compiled and executed successfully.

            For j = 0 To 2 Step 1
                sum = sum + arr(i, j)
            Next
            Console.WriteLine("Sum of row {0}: {1}", i, sum)
        Next
    End Sub

End Module

Output

Enter Matrix elements:
Enter element[0][0]: 10
Enter element[0][1]: 20
Enter element[0][2]: 30
Enter element[1][0]: 40
Enter element[1][1]: 50
Enter element[1][2]: 60
Matrix elements:
10 20 30
40 50 60
Sum of row 0: 60
Sum of row 1: 150

Explanation

In the above program, we created a module Module1 that contains a function Main(). In the Main() function, we created a two-dimensional array of size 2X3.

Console.WriteLine("Enter Matrix elements: ")
For i = 0 To 1 Step 1
    For j = 0 To 2 Step 1
        Console.Write("Enter element[{0}][{1}]: ", i, j)
        arr(i, j) = Integer.Parse(Console.ReadLine())
    Next
Next

In the above code, we read the elements of the matrix from the user, here the outer loop represents the rows of the matrix and the inner loop is used to represent columns of the matrix.

Console.WriteLine("Matrix elements: ")
For i = 0 To 1 Step 1
    For j = 0 To 2 Step 1
        Console.Write("{0} ", arr(i, j))
    Next
    Console.WriteLine()
Next

For i = 0 To 1 Step 1
    sum = 0
    For j = 0 To 2 Step 1
        sum = sum + arr(i, j)
    Next
    Console.WriteLine("Sum of row {0}: {1}", i, sum)
Next

In the above code, we calculated the sum of rows of Matrix elements and then printed the 2X3 matrix on the console screen.
