Question 1

The______ property of a ListBox's Items property is used to access values in the ?ListBox.&#10;A) Value&#10;B) Item&#10;C) List&#10;D) Row&#10;E) None of the above.

Accepted Answer

The "Item" property of a ListBox's Items property is used to access values in the ListBox. This property allows for indexing into the collection to retrieve specific items.

Question 2

The do while statement differs from a while statement in that_____ .&#10;A) a do while statement cannot enter an infinite loop&#10;B) a do while statement can use a counter but a while cannot&#10;C) the body of a while statement will execute at least once&#10;D) the body of a do while statement will execute at least once&#10;E) All of the above.

Accepted Answer

The body of a do while loop is guaranteed to execute at least once because the condition is checked after the body of the loop has been executed. This is the key difference from a while loop, where the condition is checked before the loop body executes, potentially resulting in zero executions if the condition is not met initially.

Question 3

Assume that intCounter is an int variable initialized to 5. Which of the following loop continuation conditions can be used in a do while statement to print the values 5 through 15, inclusive?&#10;A) intCounter > 5&#10;B) intCounter < 15&#10;C) intCounter <= 15&#10;D) intCounter < 16&#10;E) Both c and d.

Accepted Answer

Both conditions C) intCounter <= 15 and D) intCounter < 16 will allow the loop to iterate until intCounter reaches 15, inclusive. Condition C checks if intCounter is less than or equal to 15, and condition D checks if intCounter is less than 16, which effectively means the same thing in this context.

Question 4

When a Button is disabled,_____ .&#10;A) its text displays in a gray color&#10;B) it is no longer visible&#10;C) its Enabled property is set to True&#10;D) its Click event is not raised when the Button is clicked&#10;E) Both a and d.

Accepted Answer

When a Button is disabled, its text typically displays in a gray color to visually indicate that it is not active, and its Click event is not raised when the Button is clicked, because it cannot respond to user interactions in its disabled state.
