VB.Net program to merge two integer arrays into a third array

Here, we are going to learn how to merge two integer arrays into a third array in VB.Net?
Submitted by Nidhi, on December 07, 2020

Here, we will create two arrays of integers and then merge both arrays into a third array.

Program/Source Code:

The source code to merge two integer arrays into the third array is given below. The given program is compiled and executed successfully.

'VB.Net program to merge two integer arrays 
'into the third array.

Module Module1

    Sub Main()
        Dim arr1 As Integer() = New Integer(5) {}
        Dim arr2 As Integer() = New Integer(5) {}
        Dim arr3 As Integer() = New Integer(10) {}

        Console.WriteLine("Enter array1 elements: ")
        For i As Integer = 0 To 4 Step 1
            Console.Write("Element[{0}]: ", i)
            arr1(i) = Integer.Parse(Console.ReadLine())
        Next

        Console.WriteLine("Enter array2 elements: ")
        For i As Integer = 0 To 4 Step 1
            Console.Write("Element[{0}]: ", i)
            arr2(i) = Integer.Parse(Console.ReadLine())
        Next

        'Merge arr1 and arr2. and assigned to arr3.
        For i As Integer = 0 To 9 Step 1
            If (i <= 4) Then
                arr3(i) = arr1(i)
            Else
                arr3(i) = arr2(i - 5)
            End If
        Next

        Console.WriteLine("Merged array: ")
        For i As Integer = 0 To 9 Step 1
            Console.Write("{0} ", arr3(i))
        Next
        Console.WriteLine()
    End Sub
    
End Module

Output:

Enter array1 elements:
Element[0]: 12
Element[1]: 13
Element[2]: 4
Element[3]: 34
Element[4]: 35
Enter array2 elements:
Element[0]: 23
Element[1]: 56
Element[2]: 64
Element[3]: 64
Element[4]: 34
Merged array:
12 13 4 34 35 23 56 64 64 34 
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1 that contains a function Main().

Dim arr1 As Integer() = New Integer(5) {}
Dim arr2 As Integer() = New Integer(5) {}
Dim arr3 As Integer() = New Integer(10) {}

In the Main() method we created two arrays arr1 and arr2 of five elements, and arr3 of 10 elements.

Console.WriteLine("Enter array1 elements: ")
For i As Integer = 0 To 4 Step 1
    Console.Write("Element[{0}]: ", i)
    arr1(i) = Integer.Parse(Console.ReadLine())
Next

Console.WriteLine("Enter array2 elements: ")
For i As Integer = 0 To 4 Step 1
    Console.Write("Element[{0}]: ", i)
    arr2(i) = Integer.Parse(Console.ReadLine())
Next

In the above code, we read the elements of arr1 and arr2 from the user.

'Merge arr1 and arr2. and assigned to arr3.
For i As Integer = 0 To 9 Step 1
    If (i <= 4) Then
        arr3(i) = arr1(i)
    Else
        arr3(i) = arr2(i - 5)
    End If
Next

Console.WriteLine("Merged array: ")
For i As Integer = 0 To 9 Step 1
    Console.Write("{0} ", arr3(i))
Next

In the above code, we merged arr1 and arr2 into arr3, and print the merged array on the console screen.
