Constructs

Question 1

abstract step

Answer 1

a high-level action in an algorithm that describes what needs to be done without detailing how to do it

Question 2

algorithm

Answer 2

a step-by-step set of instructions designed to perform a specific task or solve a problem

Question 3

branch

Answer 3

a point in an algorithm where a decision is made, leading to different actions based on conditions (e.g., if-then statements)

Question 4

infinite loop

Answer 4

a loop that never ends because the termination condition is never met or is incorrectly written

Question 5

input

Answer 5

data that are provided to a program for processing

Question 6

loop control variable

Answer 6

a variable that determines whether the loop will continue running or stop, often incremented or modified within the loop

Question 7

nested structure

Answer 7

a programming construct where one control structure (like a loop or a conditional statement) is placed inside another

Question 8

output

Answer 8

data that are produced by a program and presented to the user or another system

Question 9

pretest loop

Answer 9

a loop that evaluates its condition before executing the body of the loop, such as a while loop

Question 10

pseudocode

Answer 10

A simplified, human-readable version of a program’s code that outlines the logic without strict syntax rules

Question 11

repetition (iteration)

Answer 11

the act of executing a set of instructions multiple times, typically using loops

Question 12

selection

Answer 12

a control structure that allows a program to choose between different actions based on conditions (similar to a branch)
