Customer Question

You have been asked to develop an application with the following business requirements: The user will enter an order quantity, which must be a whole number. When the user clicks a Calculate New Quantity button, the application will calculate a new order quantity by adding 10 to the original order quantity. The application will display the new order quantity to the user.
(a) Develop a TOE chart for this application. You do not need to put it in table form, but list what would go in the Task column, what would go in the Object column, and what would go in the Event column for each row of the chart. Your chart should have at least three rows: one for input, one for processing, and one for output.
(b) Write pseudocode for the button-click event procedure in this application.
(c) Identify two variables and one constant that you would declare for this application. For each, provide a variable or constant name that follows the syntax rules of Visual Basic and the Hungarian naming convention, and an appropriate Visual Basic data type.
Consider the following Visual Basic code snippet:
If intScore >= 100 Then
lblMessage.Text = "Great job!"
ElseIf intScore >= 50 Then
lblMessage.Text = "Good work"
lblMessage.Text = "Better luck next time"
End If
(a) What type of control structure is this? Be as specific as possible, and justify your answer.
(b) Describe step by step how this code will be executed and what will be displayed to the user for each of the following values of intScore: 25, 75, and 125.
(c) Rewrite this code snippet using a Select Case statement instead of If . . . Then . . . ElseIf . . . Else.
Consider the following code snippet:
Dim intTotal As Integer = 0
For intNum As Integer = 1 To 5
intTotal += intNum
Next intNum
MessageBox.Show( intTotal.ToString() )
(a) What type of control structure is this? Be as specific as possible, and explain your answer.
(b) Identify the counter variable and the accumulator variable in this loop. Explain your answer.
