Add two matrices

Here, we will read two matrices from the user then add both matrices and assigned them to another matrix. After that, we will all matrices on the console screen.

Program/Source Code:

The source code to add two matrices is given below. The given program is compiled and executed successfully.

Explanation

In the above program, we created a module Module1 that contains a function Main(). In the Main(), we created three matrices of 2x2 using a two-dimensional array.

Console.WriteLine("Enter Matrix1: ")
For i = 0 To 1 Step 1
    For j = 0 To 1 Step 1
        Console.Write("Enter element[{0}][{1}]: ", i, j)
        matrix1(i, j) = Integer.Parse(Console.ReadLine())
    Next
Next

Console.WriteLine("Enter Matrix2: ")
For i = 0 To 1 Step 1
    For j = 0 To 1 Step 1
        Console.Write("Enter element[{0}][{1}]: ", i, j)
        matrix2(i, j) = Integer.Parse(Console.ReadLine())
    Next
Next

In the above code, we read elements for both matrices from the user.

'Add Matrix1 and Matrix2
For i = 0 To 1 Step 1
    For j = 0 To 1 Step 1
        matrix3(i, j) = matrix1(i, j) + matrix2(i, j)
    Next
Next

Here, in the above code, we add matrix1 and matrix2 and assigned the addition of both matrices into matrix3. After that, we printed the all matrices on the console screen.
