Creating algorithms unit 1

Question 1

What are the three main programming constructs used in algorithms?

Answer 1

Sequence, Selection, and Iteration.

Question 2

What is the sequence construct?

Answer 2

It means the instructions are executed in the exact order they are written.

Question 3

What is the selection construct?

Answer 3

It allows decision-making in algorithms, using conditions to choose different paths (e.g., IF…ELSE statements).

Question 4

What is the iteration construct?

Answer 4

It repeats steps using loops (e.g., FOR, WHILE) until a condition is met.

Question 5

Why are sequence, selection, and iteration important?

Answer 5

They are the basic building blocks of all algorithms.

Question 6

What is the first step in creating an algorithm to solve a problem?

Answer 6

Understand the problem and break it down into smaller steps.

Question 7

What are the different ways to represent an algorithm?

Answer 7

Flowchart, pseudocode, written description, or draft program code.

Question 8

What is a flowchart used for in algorithms?

Answer 8

To visually show the steps and logic of an algorithm using symbols and arrows.

Question 9

What is pseudocode useful for?

Answer 9

Describing the logic of an algorithm in a clear, readable, code-like way.

Question 10

What is a draft program code?

Answer 10

A rough version of the actual code, used to test and build the algorithm in a real programming language.
