Question

What happens in this click event?

Private Sub btnDisplay_Click(...) Handles btnDisplay.Click

Dim flag As Boolean

Dim a As Integer = 10

Dim num As Integer

num = a Mod 5

Do While flag = False

a += num

If a * num <> 0 Then

flag = True

End If

Loop

txtOut.Text = CStr(a)

End Sub

an infinite loop

What is the output of following-
   Private Sub btnDisplay_Click(...) Handles btnDisplay.Click
     Dim row As String = ""
     For i as Integer = 1 to 9
       row &= "*"
     Next
     txtOutput.Text = row
   End Sub

DIsplays a column of nine numbers.

What should you use- if the exact number of times the loop will be executed is known before entering the loop?

Do While loop.

2 Arrays with a double datatype of 31 elements have been declared backUpArry(30) and resultsArry(30). The resultsArry() will be used for further calculations and the backUpArry() will be saved. Assign the value of resultsArry() into backUpArry().

resultsArry.CopyTo(backUpArry,0)

One hundred more items have to be added salesDataArry(). The current 101 values are important and must be maintained. Choose the correct statement to prepare the array.

redim reserve salesDataArry(200)

Private Sub btnDisplay_Click( . . . ) Handles btnDisplay.Clicked.

Dim spoon(num) As String

Spoon(0) = “soup”
