    List boxes and combo boxes _______.

    • Are created with the same tool from the toolbox

    • Have a Text property during design time

    • Hold a list of values

    • Always have scroll bars

    Correct Answer
    A. Hold a list of values
    Explanation
    List boxes and combo boxes hold a list of values. They are used to display a set of options from which the user can select one or multiple values. The main difference between them is that a list box displays all the options at once, while a combo box initially displays only one option and allows the user to expand it to see the full list. Both list boxes and combo boxes can be created using the same tool from the toolbox and have a Text property during design time, but the key characteristic is that they hold a list of values.

    Rate this question:

  • 5. 

    Items can be added to a list during design time using the _________ collection.

    • AddLists

    • Items

    • ItemsAdd

    • AddItems

    Correct Answer
    A. Items
    Explanation
    During design time, items can be added to a list using the "Items" collection. This collection allows for the addition of items to the list before the program is executed or run. It provides a convenient way to populate the list with initial data or values.

    Rate this question:

  • 6. 

    Values for the items in a list _______.

    • Can be entered in the Items collection in the Properties window

    • Can be entered in the Values collection in the Properties window

    • During design time in the Items Collection of the combo box

    • Using the ComboBox.Add() method

    • Answers A and B are correct

    Correct Answer
    A. Answers A and B are correct
    Explanation
    The data that appears in a combo box when it is first displayed can be added to the combo box using the Form_Load procedure and the combo box Items.Add method, as well as during design time in the Items Collection of the combo box. Both methods can be used to populate the combo box with the desired data before it is displayed to the user.

    Rate this question:

  • 8. 

    Items can be added to a list during run time using the _________ method.

    • AddLists

    • Lists

    • ItemsAdd

        40.   Items in a list can be placed in alphabetical order by _______.

    • Setting the Sorted property to True

    • Selecting the item in the list and then using the arrow keys to move the item up or down the list

    • Setting the Alphabetize property to True

    • Setting the Index property to 1

    Correct Answer
    A. Setting the Sorted property to True
    Explanation
    To place items in a list in alphabetical order, you can set the Sorted property to True. This property automatically arranges the items in the list in alphabetical order based on their values. This means that as you add or modify items in the list, they will automatically be sorted in the correct order. The other options mentioned in the question, such as using the arrow keys or setting other properties, are not specifically designed for alphabetical sorting.

    Rate this question:

  • 10. 

    Which of the following instructions will add the word, monkey, to a list box named animalsListBox?

    • AnimalsListBox.Insert(monkey)

    • AnimalsListBox.Insert (“monkey”)

    • AnimalsListBox.Items.Add(monkey)

    • AnimalsListBox.Items.Add(“monkey”)

    Correct Answer
    A. AnimalsListBox.Items.Add(“monkey”)
    Explanation
    The correct answer is animalsListBox.Items.Add("monkey"). This is because the Items property of the animalsListBox is used to add an item to the list box, and the parameter passed to the Add method should be a string, in this case "monkey".

    Rate this question:

  • 11. 

    The code that will add the name, John, to a combo box named namesComboBox is _______.

    • NamesComboBox.Items.Add (“John”)

    • NamesComboBox.AddItem = (“John”)

    • Add.namesComboBox = (“John”)

    • Add.”John”.namesComboBox

    Correct Answer
    A. NamesComboBox.Items.Add (“John”)
    Explanation
    The correct answer is namesComboBox.Items.Add ("John"). This code will add the name "John" to the combo box named namesComboBox by using the Add method of the Items property.

    Rate this question:

  • 12. 

    The SelectedIndex property of the first item in a list is _______.  

    • -1

    • 0

    • 1

    • True

    Correct Answer
    A. 0
    Explanation
    The SelectedIndex property of the first item in a list is 0 because the index of the first item in a list is always 0 in most programming languages. This means that when the first item is selected, the SelectedIndex property will be set to 0.

    Rate this question:

  • 13. 

    What is the value of the SelectedIndex property if the user has not selected an item from a combo box?

    • -1

    • 0

    • 1

    • None of the above

    • Emphasize the luxurious circumstances of Tess’s life with Alec

    • Introduce the detail of the missing carving knife

    • Show the haste in which Tess had left the lodging house

    • Establish that Mrs. Brooks was a generous landlady

    • Present a scene of a comfortable domestic routine

    Correct Answer(s)
    A. -1
    A. Introduce the detail of the missing carving knife
    Explanation
    The value of the SelectedIndex property is -1 if the user has not selected an item from a combo box. This value indicates that no item has been selected. The other options provided in the question are unrelated and do not provide an explanation for the correct answer.

    Rate this question:

  • 14. 

    What is the value of the SelectedIndex property if the user has selected the last item in a list with four items?

    • 3

    • 4

    • 5

    • 0

    Correct Answer
    A. 3
    Explanation
    The value of the SelectedIndex property is 3 if the user has selected the last item in a list with four items. This is because the index of the first item in the list is 0, and the index of the last item is one less than the total number of items in the list. Therefore, if there are four items in the list, the index of the last item would be 3.

    Rate this question:

  • 15. 

    Which of the following code examples can be used to determine the number of items in a list box named colorListBox?

    • ColorListBox.Count.Index

    • ColorListBox.Items.Count

    • ColorListBox(Items.Total)

    • ColorListBox.SelectedIndex

    Correct Answer
    A. ColorListBox.Items.Count
    Explanation
    The correct answer is colorListBox.Items.Count. This code example can be used to determine the number of items in a list box named colorListBox. The ".Items" property is used to access the collection of items in the list box, and the ".Count" property is used to retrieve the number of items in that collection.

    Rate this question:

  • 16. 

    An individual item can be deleted from a list with the _______.

    • Items.Delete method

    • Items.Clear method

    • Items.Erase method

    • Items.RemoveAt method

    Correct Answer
    A. Items.RemoveAt method
    Explanation
    The Items.RemoveAt method is used to delete an individual item from a list. This method removes the item at the specified index position in the list, effectively shifting all subsequent items down by one position. This allows for the removal of a specific item without affecting the rest of the list.

    Rate this question:

  • 17. 

    The code to delete the selected item from colorListBox is _______.

    • ColorListBox.Clear

    • ColorListBox.RemoveItem

    • ColorListBox.Delete (colorListBox.ListIndex)

    • ColorListBox.Items.RemoveAt (colorListBox.SelectedIndex)

    Correct Answer
    A. ColorListBox.Items.RemoveAt (colorListBox.SelectedIndex)
    Explanation
    The correct answer is colorListBox.Items.RemoveAt (colorListBox.SelectedIndex). This code removes the item at the selected index from the colorListBox control.

  • 20. 

    The process of repeating a series of instructions is called ______________.

    • Repetition

    • Reiteration

    • Looping

    • Initializing

    Correct Answer
    A. Looping
    Explanation
    The process of repeating a series of instructions is called looping. In programming, a loop is used to execute a block of code multiple times until a certain condition is met. This allows for efficient and automated repetition, reducing the need for manual repetition of code. The other options, repetition and reiteration, are similar in meaning but do not specifically refer to the concept of repeating instructions in a programming context. Initializing, on the other hand, refers to the process of assigning an initial value to a variable.

    Rate this question:

  • 21. 

    The group of instructions that are repeated in a Do/Loop are called a(n) __________.

    • Group

    • Set

    • Loop

    • Iteration

    Correct Answer
    A. Loop
    Explanation
    In a Do/Loop, a group of instructions is repeatedly executed until a certain condition is met. This repetition is called a loop. The loop allows the instructions to be executed multiple times, helping to automate tasks and save time. Therefore, the correct answer is "loop."

    Rate this question:

  • 22. 

    A single execution of a group of instructions inside a Do/Loop is called _______.

    • An iteration

    • A loop

    • A set

    • A group

    Correct Answer
    A. An iteration
    Explanation
    In a Do/Loop, a group of instructions is executed repeatedly until a certain condition is met. Each execution of this group of instructions is called an iteration. Therefore, the correct answer is "an iteration".

    Rate this question:

  • 23. 

    The statements inside of a Do/Loop may never be executed if _______.

    • The terminating condition is at the top of the loop and it is True the first time it is tested

    • The terminating condition is at the bottom of the loop and it is True the first time it is tested

    • Both answers A and B would cause the statements in the loop not to be executed

    • The statements in the loop will always be executed

    • Had lost its beauty over time

    • Had caused her to go to Tantridge

    • Had attracted Alec to her

    • Had alienated her from her peers

    • Had shown her anguish over her baby

    Correct Answer(s)
    A. The terminating condition is at the top of the loop and it is True the first time it is tested
    A. Had attracted Alec to her
    Explanation
    If the terminating condition is at the top of the loop and it is True the first time it is tested, the statements inside the loop may never be executed. This is because the terminating condition is checked before the loop is entered, and if it is already True, the loop will not be executed at all. Therefore, the statements inside the loop will not have a chance to be executed.

    Rate this question:

  • 24. 

    The values of Boolean data types are referred to as _______.

    • Banners

    • Flags

    • Ribbons

    • Posters

    Correct Answer
    A. Flags
    Explanation
    Boolean data types in programming are used to represent true or false values. The term "flags" is often used to describe variables or values that act as indicators or signals, typically representing a true or false condition. Therefore, "flags" is an appropriate term to refer to the values of Boolean data types.

    Rate this question:

  • 25. 

    When is the counter incremented in a FOR/NEXT statement?

    • In the NEXT statement

    • In the FOR statement

    • In the Exit For statement

    • When the statements in the loop are executed

    Correct Answer
    A. In the NEXT statement
    Explanation
    The counter is incremented in the NEXT statement. This is because the NEXT statement is responsible for controlling the loop and determining when it should terminate. When the NEXT statement is reached, the counter is incremented and the loop continues until the termination condition is met. Therefore, the counter is incremented in the NEXT statement.

    Rate this question:

  • 26. 

    When is the counter tested in a FOR/NEXT statement?

    • In the NEXT statement

    • In the FOR statement

    • When the counter is initialized

    • When the counter is incremented

    Correct Answer
    A. In the FOR statement
    Explanation
    The counter is tested in the FOR statement. In a FOR/NEXT statement, the FOR statement initializes the counter and sets the initial value. The counter is then tested to see if it meets the specified condition. If the condition is true, the loop continues to execute. If the condition is false, the loop is exited and the program moves on to the next statement after the NEXT statement. Therefore, the counter is tested in the FOR statement to determine if the loop should be executed.

    Rate this question:

  • 27. 

    When does a For/Next statement terminate iteration?

    • When executing the For statement, the counter must be greater than the final value

    • When executing the For statement, the counter must be the same as the final value

    • When executing the Next statement, the counter must be greater than the final value

    • When executing the Next statement, the counter must be the same as the final value

    Correct Answer
    A. When executing the For statement, the counter must be greater than the final value
    Explanation
    The For/Next statement terminates iteration when executing the For statement, the counter must be greater than the final value. This means that the loop will continue as long as the counter is less than or equal to the final value, and it will stop once the counter becomes greater than the final value.

    Rate this question:

  • 28. 

    Incorrect indentation of the statements in For/Next loops _______.

    • Will cause the program to halt

    • Will cause the logic of calculations inside the loop to perform incorrectly

    • Will make the program difficult to read and understand

    • All of the above

    • Connotative diction

    • Convoluted syntax

    • Powerful invective

    • Historical references

    • Indirect allusion

    Correct Answer(s)
    A. Will make the program difficult to read and understand
    A. Connotative diction
    Explanation
    Incorrect indentation of the statements in For/Next loops will make the program difficult to read and understand. This is because indentation is used to visually organize the code and indicate the hierarchy of the statements. When the indentation is incorrect, it becomes harder to follow the flow of the program and understand the logic. Additionally, it can lead to confusion and mistakes when trying to modify or debug the code. Connotative diction, convoluted syntax, powerful invective, historical references, and indirect allusion are not relevant to the given question.

    Rate this question:

  • 29. 

    How many times will the statements inside this For/Next loop be executed?                 For indexInteger = 1 to 10                   'Statements in loop                 Next indexInteger

    • 2

    • 4

    • 5

    • 10

    Correct Answer
    A. 10
    Explanation
    The statements inside the For/Next loop will be executed 10 times because the loop is set to iterate from 1 to 10 (inclusive) with the statement "For indexInteger = 1 to 10". The "Next indexInteger" indicates the end of the loop. Therefore, the statements within the loop will be executed once for each value of indexInteger from 1 to 10.

    What will be the value of valueInteger after execution of these statements?             For indexInteger = 1 to 10 Step 2                 valueInteger += indexInteger             Next indexInteger

    • 20

    • 25

    • 36

    • None of the above

    Correct Answer
    A. 25
    Explanation
    The value of valueInteger will be 25 after the execution of these statements. The loop starts with indexInteger = 1 and increments by 2 in each iteration. So, in the first iteration, valueInteger will be incremented by 1, in the second iteration it will be incremented by 3, in the third iteration by 5, and so on. Therefore, the final value of valueInteger will be the sum of all odd numbers from 1 to 10, which is 25.

    Rate this question:

  • 35. 

    What will be the value of indexInteger after execution of these statements?             For indexInteger = 1 to 10 Step 2                 valueInteger = += indexInteger             Next indexInteger  

    • 10

    • 11

    • 13

    • 14

    Correct Answer
    A. 11
    Explanation
    The value of indexInteger after the execution of these statements will be 11. This is because the loop starts with indexInteger = 1 and increments it by 2 in each iteration. So, the values of indexInteger during the loop will be 1, 3, 5, 7, 9. After the loop, indexInteger is incremented by 2 one more time, resulting in a final value of 11.

    Terminate a For/Next loop with the _______ statement

    • Exit

    • ExitFor

    • ExitLoop

    • Continue

    Correct Answer
    A. ExitFor
    Explanation
    The correct answer is "ExitFor". In a For/Next loop, the "ExitFor" statement is used to prematurely terminate the loop and transfer the control to the statement immediately following the loop. This allows the program to skip the remaining iterations of the loop and continue with the execution of the code.

    Rate this question:

  • 37. 

    Skip to the next iteration of a Do loop with the _______ statement.

    • Exit For

    • Exit Do

    • Continue For

    • Continue Do

    Correct Answer
    A. Continue Do
    Explanation
    The correct answer is "Continue Do". In a Do loop, the "Continue Do" statement is used to skip the remaining code within the loop and move to the next iteration of the loop. This allows the program to bypass certain conditions or actions and continue with the next iteration of the loop.
