Question 1. 1. (TCOs 1, 2, and 3) You have been asked to develop an application with the following business
requirements: The user will enter an original price. When the user clicks a Calculate Sale Price button, the application
will calculate a sale price by multiplying the original price by 80%. The application will display the sale price to the user.
1. 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.
2. Write pseudocode for the button-click event procedure in this application.
3. 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. (Points : 30)
Question 2. 2. (TCO 5) Consider the following Visual Basic code snippet:
If intScore>= 100 Then
lblMessage.Text = “Great job!”
Else
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: 99, 100, and 101.
c. Rewrite this code snippet so that it still produces the same results, but changing the condition in the first line
from intScore>= 100 to intScore< 100. (Points : 30)
Question 3. 3. (TCO 6) 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.
c. Describe step by step how this code will be executed and what value will be displayed in a message box to
the user. (Points : 30)
Question 1. 1. (TCO 7) (a) Explain the difference between passing by value and passing by reference when passing
variables to a Sub procedure or function.
a. (b) Describe a specific example of using a Sub procedure when you would pass a variable by value.
b. Describe a specific example of using a Sub procedure when you would pass a variable by reference. (Points

Question 2. 2. (TCOs 2 and 4) You have been asked to develop an application to keep track of employees’
scheduled vacations and ensure that all vacations are approved by the manager and that each employee does not
exceed his or her maximum annual vacation time. Maximum annual vacation time is determined by the number of years
the employee has worked for the firm. You are using object-oriented programming (OOP) to develop this application.
a. Describe at least two classes that you could use in this application and what each class would represent in
the real world.
b. Describe at least two properties of each class you identified in part (a) and identify the data type you would
use for each property.
