An algorithm is written in VB.Net to validate a flight booking reference and calculate any cabin-class baggage surcharge.
Figure 1
1 Dim extraCharge As Decimal = 0.0
2 Console.Write("Enter booking reference: ")
3 Dim bookingRef As String = Console.ReadLine()
4 While bookingRef.Length() < 8
5 Dim warningText As String = " is too short for a standard reference"
6 Console.WriteLine(warningText)
7 bookingRef = Console.ReadLine()
8 End While
9 Console.Write("Enter cabin class (1 for First, 2 for Economy): ")
10 Dim cabinClass As Integer = Console.ReadLine()
11 If cabinClass = 1 Then
12 extraCharge = 0.0
13 Else
14 extraCharge = 25.0
15 End If
16 Console.WriteLine(extraCharge)
Rewrite line 5 in Figure 1 to concatenate the booking reference string stored in the variable bookingRef with the string " is too short for a standard reference", and store the result in the variable warningText.
Your answer must be written in VB.Net.
