Dim a, b, c As Integer
Dim op As String

Console.Write("Enter first number: ")
a = Convert.ToInt32(Console.ReadLine())

Console.Write("Enter second number: ")
b = Convert.ToInt32(Console.ReadLine())

Console.Write("Enter Operator: ")
op = Console.ReadLine()

If op = "+" Then
    c = a + b
ElseIf op = "-" Then
    c = a - b
ElseIf op = "*" Then
    c = a * b
ElseIf op = "/" Then
    If b = 0 Then
        Console.WriteLine("Division by zero is not allowed")
        c = a / b
    End If
    Console.WriteLine("Invalid operator")
End If

Console.WriteLine("Answer = " & c)
