1
How does a Do-Until loop function compare to a Do-While loop?
one loop is when the condition is checked, the other checks before the body
one is designed to run while a condition is satisfied. other returns false
2

sum of a set of items
adding up the total number of items in a list or a set

cybersecurity threat detection and investigation
used to check if an input is good
4
Describe the difference between a while loop and a Do-While loop
A loop that executes at least once while one might not execute at all
one loop is used at before it starts while the other one does it after
5
What is the benefit of using repetition structures instead of writing the same code repeatedly?
adds more lines on the code
improving readability
reduces time spent on code
6
What is a count-controlled loop?
executes a block of code a predetermined number of times
executes a block of code as long as a specified condition remains true.
a block of code to be executed repeatedly
7
What is one key point to remember to avoid creating an infinite loop?
ensure your loop's condition can eventually become false
a condition that will never become false.
a condition that is always true
while (1 == 1):
8
What is a sentinel?
a special value used to signal the end of a sequence or data
a piece of code that while break the code segment
9
What is the main purpose of using repetition structures in programming
To Execute a block of code multiple times without repeatedly writing it
to contain or hold something, so it is not all over the place
