Reads value from the user in Visual Basic Console App

Imports System 'Include the system namespace in our program.'

Module Program 'Module of a class that contains the data and procedures.'
Dim num1 As Integer 'Dim statement is used for variable declaration and storage allocation for one or more variables.'
Sub Main() 'Indicates the entry point'
num1 = Console.ReadLine() 'ReadLine for accepting input from the user and store it into a variable(num1).'

End Sub
End Module

Display input from to user in Visual Basic Console App

Imports System

Module Program
Dim num1 As Integer

Sub Main()
num1 = Console.ReadLine()

Console.WriteLine(num1) 'WriteLine is used to output the stream'

End Sub
End Module

* Dim num1 As Integer it only takes an Integer value as a input, If we try to pass an string it through an error => Conversion from string "String" to type 'Integer' is not valid.
