representation of
decisions and their
conditions
To eliminate the need for decision-making C
49
an example of a decision that can be
modeled using a flowchart?
Choosing a
favorite movie
Selecting the
winning lottery
numbers
Deciding whether
to take an
umbrella based on
the weather
forecast
Solving a complex mathematical problem C
50
What is the primary goal of decision-
making in problem solving?
To complicate
problems
To avoid
making choices
To reach the best
possible solution
or outcome
To eliminate all options except one C
51
What is the primary purpose of using
loops in problem solving?
To make the code
more complex
To perform
mathematical
calculations
To execute a
block of code
repeatedly based
on a condition
To avoid solving problems C

52
Which type of loop continues to execute
as long as a specified condition is true?
For loop While loop Do-while loop Switch loop B
53
In programming, what is
the purpose of a "for" loop?
To create an
infinite loop
To execute a
block of code at
least once
To iterate over a
range of values
and control the
loop with a
counter
To execute a block of code only if a
condition is true
C
54
What is the key difference between a
"while" loop and a "do-while" loop?
A "while" loop
always executes
its code block at
least once.
A "do-while"
loop always has
a counter.
A "do-while"
loop checks the
condition before
executing the code
block.
A "while" loop cannot be used in
programming.
C
55
What is the term for a loop that repeats
indefinitely until a specific condition is
met?
Infinite loop
Conditional
loop
Counter loop Nested loop A
56
In a "for" loop, what is the role of the
loop counter variable?
It controls the
condition of the
loop.
It stores the
result of the
loop.
It keeps track of
the number of
iterations.
It terminates the loop. C
57
Which loop is best suited
for situations where the loop body must
always execute at least once?
For loop While loop Do-while loop Nested loop C
58
What is the term for a loop
inside another loop?
Nested loop Recursive loop Infinite loop Conditional loop A
59
What is the primary goal of
loop control statements such as "break"
and "continue"?
To make the
loop execute faster
To exit the
program
To modify the
loop counter
To alter the flow of the loop D
60
In problem solving with
loops, what does "iteration" refer to?
A single
execution of the
loop body
The total
number of loops
used in a
program
The loop counter
variable
A loop that contains nested loops A
