Question 1

What is a Algorithm?

Answer 1

An algorithm is a set of clear steps to complete a task. It can be written in different ways, like natural language, pseudocode, or flowcharts. Algorithms are important because they tell computers and programs what to do with data.

Question 9

what command Changes the color of the drawing pen where c is the name of a color such as “red”, “blue”, and “yellow.”?

Answer 9

painter.pencolor(c)

Question 10

Answer 12

painter.turtlesize(s)

Question 13

What does user input mean?

Answer 13

User input in computer science refers to any data or information that a user provides to a computer or program. This input can be given through various devices like a keyboard, mouse, touch screen, or voice commands, and it allows the user to interact with the system or influence its behavior.
ex:user_name = input(“What is your name?”)
print(“Hello”, user_name, “welcome to my program.”)

What is a advance way you can make a circle?

Answer 14

painter.forward(30)
painter.right(20)

Question 15

While Loops

Answer 15

a control flow statement that allows code to be executed repeatedly based on a given condition. The loop continues to execute the block of code as long as the condition remains true. Once the condition becomes false, the loop terminates.

Question 16

For Loops

Answer 16

used to iterate over a sequence (like a list, tuple, or string) or other iterable objects. Iterating over a sequence means going through each element one by one.

Question 17

Nested Loops

Answer 17

one or more loops within the body of another loop. The two loops are referred to as outer loop and inner loop. The outer loop controls the number of the inner loop’s full execution. More than one inner loop can exist in a nested loop.

Question 18

Modulo operator

Answer 18

is a way to determine the remainder of a division operation. Instead of returning the result of the division, the modulo operation returns the whole number remainder.

Question 19

Answer 20

Use descriptive names that convey the purpose, meaning, or role of the variable.

Question 21

Lists

Answer 21

An ordered collection of items or values.

Question 22

If/else statements

Answer 22

A feature of a programming language that performs different computations or actions depending on whether a Boolean condition evaluates to true or false.

Question 23

Functions

Answer 23

a block of statements that return the specific task.

Question 24

On Key press

Answer 24

a command that only works when a certain keybind is pressed

Question 25

Pseudocode

Answer 25

a way of expressing an algorithm without conforming to specific syntax rules.

Question 26

Phishing / malicious content

Answer 26

Practice of sending fraudulent emails that appear to be from legitimate companies with the intent to induce people to share sensitive information, such as passwords and credit card numbers.

Question 27

Password encryption

Answer 27

The process of encoding data to prevent unauthorized access, such as converting plaintext to ciphertext.

Question 28

What are some ways you can create a strong password

Answer 28

adding symbols and captialize certain letters, not using the same password you have for other places, not using personal info in your password

Question 29

User Interface

Answer 29

An interface defines a contract between a class and its users. It specifies a set of methods that a class must implement in order to be considered compatible with the interface.

Question 30
