Question #268003
1. Consider the following code segments using the Boolean variables a, b, c and d.
If Not c Or d Then
If a And c Then
lblOut.Text = “1”
ElseIf b Then
lblOut.Text = “2”
Else
lblOut.Text = “3”
End If
ElseIf Not c = d Then
lblOut.Text = “4”
ElseIf c Then
lblOut.Text = “5”
Else lblOut.Text = “6”
End If
a. Give the values for a, b, c and d that will cause the above code segment to display 1 in lblOut.
b. Give the values for a, b, c and d that will cause the above code segment to display 4 in lblOut.
2. Write VB.NET code that will use a loop to calculate the sum of all integer numbers between 5 and 100 that are divisible by both 5 and 6.
You may choose to use any looping structure.
Use the following variable declarations.
Dim intCounter As Integer ‘loop counter variable
Dim intSum As Integer ‘to accumulate the summation
Expert's answer
a. Give the values for a, b, c and d that will cause the above code segment to display 1 in lblOut.
a = True
b = False
c = True
d = True
b. Give the values for a, b, c and d that will cause the above code segment to display 4 in lblOut.
a = True
b = False
c = True
d = False
2. Write VB.NET code that will use a loop to calculate the sum of all integer numbers between 5 and 100 that are divisible by both 5 and 6.
Imports System.IO
Module Module1
Sub Main()
Dim intCounter As Integer ‘loop counter variable
Dim intSum As Integer 'to accumulate the summation
intCounter = 5
intSum = 0
While intCounter <= 110
If intCounter Mod 5 = 0 And intCounter Mod 6 = 0 Then
intSum += intCounter
End If
intCounter += 1
End While
Console.WriteLine("Sum " + intSum.ToString())
Console.ReadLine()
End Sub
End Module
