Expert Answer


Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new console application in VB.net is created in Visual Studio 2017 with name “Demo_Vectors“.This application contains a module with name “module1“.Below is vb.net code for this module.


Module Module1
‘declaring array of integers
‘array for first vector
Dim firstVector(30) As Integer
‘array for second vector
Dim secondVector(30) As Integer
‘array for third vector
Dim resultVector(30) As Integer
‘declaring variable i of integer type

Dim i As Integer
‘main method
Sub Main()
‘asking user to enter numbers for firstVector
Console.WriteLine(“Enter Numbers for firstVector”)
‘for loop that goes from 0 to 29
For i = 0 To firstVector.Length – 2
‘displaying message to user
Console.Write(“Enter {0} Number :”, i + 1)
‘reading and parsing number from console and storing it in firstVector
firstVector(i) = Integer.Parse(Console.ReadLine())
‘asking user to enter numbers for secondVector
Console.Write(“Enter Numbers for secondVector”)
‘for loop that goes from 0 to 29
For i = 0 To secondVector.Length – 2
‘displaying message to user
Console.Write(“Enter {0} Number :”, i + 1)
‘reading and parsing number from console and storing it in secondVector
secondVector(i) = Integer.Parse(Console.ReadLine())
‘displaying message on the console
Console.WriteLine(“Addition of two vector”)
‘for loop that goes from 0 to 29
For i = 0 To resultVector.Length – 2
‘adding numbers from firstVector and secondVector
‘and storing it in third resultVector
resultVector(i) = firstVector(i) + secondVector(i)
‘displaying result on the console
Console.Write(“{0} “, resultVector(i))
End Sub
End Module
