Question
Use the code below to answer the next three questions: Private Sub ban Compute_Click (... Dim n As Integer Dim y As Integer n = Clnt (txtNumber.Text) y = Mystery (n) IstOut.ltems.Add (y) lstOut.Items.Add (Mystery(y)) End Sub Private Function Mystery (By Val v As Integer) As Integer Return v * v End Function What is the output if the user enters 4 in the text box? 4 16 4 16 4 32 16 256 Which statement is not true about function Mystery? Parameter v receives the value of the supplied argument. The scope of v is restricted to the code within Function Mystery. Function Mystery is passed one Integer value and returns an Integer result. Since function Mystery is called twice in subroutine btnCompute_Click. parameter v is only created once in memory to speed up processing. Which of the following is not a valid way to call function Mystery? Assume bloat is a label y = Mystery (43) lblout= Mystery (y + 5) IblOut Text = Mystery (Mystery (3)) All choices a)-c) are valid. Which function heading should be used for a Function that is passed the width and length of rectangle and returns its area? Private Function Area () As Double Private Function Area (By Val sidle. side2 As Integer) As Integer Private Function Area (By Val x As Integer, By Val y As Integer) Private Function Area (By Val sl As Integer. By Val s2 As Integer) As IntegerExplanation / Answer
Answers with Explanations:
7)16
256
Ans: d
The Function Mystery takes the value 4 into v in first iteration
and it will calculates 4*4 then returns the result = 16.
The Function Mystery takes the value 16 into v in second iteration
and it will calculates 16*16 then returns the result = 256.
So ,Finally the result is 16
256.
8)
Ans :d
Since function Mystery is called twice in subroutine btnCompute_click, parameter v is only
created once in memory to speed up processing is false.
9)
Ans: a
a) y = Mystery(43), Mystery taking the integer value and the result is store into integer y, So it is valid.
10)
Ans: d
Private Function Area(ByVal s1 as Integer,ByVal s2 As Integer) As Integer
This function heading is valid for taking width and height as integer and returning result as integer.
For example :
Function call should be as follows:
Dim width As Integer
Dim height As Integer
Dim ar As Integer
ar =Area(width,height);
