Question 1

are the statements that controls the execution of the program based on the specified condition

it is useful for determining whether a condition is true or not

Answer 1

Control statements

Question 2

it is the simplest form of control statement, frequently used in decision making and changing the control flow of the program execution

Answer 2

if-then statement

Question 3

can be followed by an optional Else statement, which executes when the Boolean expression is false

Answer 3

If-then-else statement

Question 4

provides a choice to execute only one condition or statement from multiple statements

Answer 4

if-then-elseif statement

Question 5

allows a variable to be tested for equality against a list of values.

Answer 5

select case

Question 6

must evaluate to any of the elementary data type in VB.NET, boolean, byte, char, date, double etc

Answer 6

expression

Question 7

list of expression clauses representing match values for expression

Answer 7

expressionlist

Question 8

following case that run if the select expression matches any clause in expressionlist

Answer 8

statements

Question 9

statements following Case Else that run if the select expression does not match any clause in the expressionlist of any of the Case statements.

Answer 9

elsestatements

Question 10

is triggered automatically when the user selects a different item in the ComboBox

Answer 10

SelectedIndexChanged

Question 11

are fundamental for tasks that require repetition, such as iterating through collections, processing data, or performing calculations multiple times

Answer 11

Looping Statements

Question 12

determines whether the loop will continue or terminate
represented by a diamond-shaped box

Answer 12

condition

Question 13

will execute repeatedly as long as the condition remains true
represented by a rectangular box

Answer 13

Conditional code

Question 14

it repeats the enclosed block of statements while a boolean condition is true or until the condition becomes true.

it could be terminated at any time with the Exit Do statement

Answer 14

Do Loop

Question 15

continues until the specified condition is true. This loop is useful when you want to execute code until a certain condition is met

Answer 15

Do until loop

Question 16

executes as long as the specified condition is true. It’s useful when the number of iterations is not known beforehand. Similar to the While Loop, but it can also be structured yo ensure the code block executes at least once.

Answer 16

Do While Loop

Question 17

This keeps the UI responsive during the loop

Answer 17

Application.DoEvents()

Question 18

This pauses the loop for half a second, making the easier to see the updates

Answer 18

Thread.Sleep()

Question 19

is used to execute a block of code a specific number of times. it’s particularly useful for iterating over a range of values or performing repetitive tasks.

Answer 19

For Next Loop

Question 20

used to mark the end of a For…Next Loop. It indicates that the loop should continue or terminate based on the conditions defined in the loop

Answer 20

Next

Question 21

is used to iterate over a collection or an array

this loops allows you to process each item in the collection without needing to manage the index manually, making it simple and cleaner for working with collections.

Answer 21

For Each… Next Loop

Question 22

a variable that represents the current element in the collection during each iteration

Answer 22

item

Question 23

the collection or array you want to iterate over

Answer 23

collection

Question 24

is used to execute a blocks of code repeatedly as long as a specified condition is true.

it is useful when the number of iterations is not known beforehand and you want to continue executing the code until a certain condition changes

Answer 24

While End Whileloop

Question 25

This is a boolean expression that is evaluated before each iteration of the loop. if it evaluates to true, the code inside the loop will execute. If it evaluates to false, the loop will terminate

Answer 25

condition

Question 26

this is the section of code that will run as long as the condition is true.

Answer 26

code block

Question 27

is used in conjuction with the With statement to simplify code that manipulates an object.

Answer 27

End with

Question 28

allows you to execute a series of statements on a specified object without repeatedly referencing the object

Answer 28

with statement

Question 29

this keyword introduces the block, specifying the object to work with

Answer 29

With

Question 30

this is the instance of the class or object you are working on.

Answer 30

object

Question 31

this keyword closes the block

Answer 31

End With

Question 32

refer to placing one loop inside another. This structure allows you to perform complex iterations over data sets, such as multi-dimensional arrays or combinations of items.

Answer 32

Nested Loops
