& SOLUTIONS 2026 LATEST UPDATE!!
control structure - ANSWERA logical design that controls the order in which statements
execute.
sequence structure - ANSWERA set of statements that execute in the order that they
appear.
decision structure - ANSWERExecute statements only under certain circumstances.
if-else - ANSWERWill execute one block of statement if its Boolean expression is true or
another block if its Boolean expression is false.
AND - ANSWER&&
OR - ANSWER||
NOT - ANSWER!
AND operator - ANSWERBoth subexpression must be true for the compound
expression to be true.
OR operator - ANSWEROne or both subexpression must be true for the compound
expression to be true.
NOT operator - ANSWERIt negates (reverses) the value to its opposite one.
< - ANSWERLess than
> - ANSWERGreater than
>= - ANSWERGreater than or equal to
<= - ANSWERLess than or equal to
== - ANSWERequal to
!= - ANSWERnot equal to
flag - ANSWERA variable that signals when some condition exists in the program
String.Compare - ANSWERCompares two strings
, TryParse - ANSWERCan prevent exceptions caused by users entering invalid data, but
it does not check the integrity of the data.
out - ANSWERRequired in TryParse command because it specifies that the
targetVariable is an output variable
input validation - ANSWERThe process of inspecting data that has been entered into a
program to make sure it is valid before it is used.
radio buttons - ANSWERAllows users to select one choice from several possible
choices. (Clicking on a radio button, the program automatically deselects any others.
This is known as mutually exclusive selection.)
check boxes - ANSWERAllows users to select multiple options
switch - ANSWERLets the value of a variable or an expression determine which path of
execution the program will take.
testExpression - ANSWERA variable or an expression that given an integer, string, or
bool value. Yet, it cannot be a floating-point or decimal value.
list box - ANSWERDisplays a list of items and allow the user to select an item from the
list.
SelectedItem - ANSWERGets or sets the currently selected item in the ListBox. When
the user selects an item, the item is stored in this property.
SelectedIndex - ANSWERGets or sets the zero-based index of the currently selected
item in a ListBox.
Items.Add - ANSWERAllows you to add an item to the ListBox control.
Items.Clear - ANSWERCan erase all the items in the Items property.
count - ANSWERReports the number of items stored in the ListBox.
while loop - ANSWERCauses a statement or set of statements to repeat as long as a
Boolean expression is true. It tests its condition before performing an iteration. It is
necessary to declare a counter variable with initial value.
iteration - ANSWEREach time the loop executes its statement or statements.
while clause - ANSWERThe first line of a while loop
infinite loop - ANSWERA loop that will repeat until the program is interrupted.
