What is sequencing in coding?

• The process of creating a new code

• The act of debugging a program

• The method of organizing files in a computer

• The specific order in which instructions are executed.

Why is sequencing important in coding?

• To determine the order in which instructions are executed

• To confuse the programmer

• To make the code run faster

• To add more complexity to the code

What is debugging code?

• Writing new code without checking for errors

• Identifying and fixing errors or bugs in a computer program.

• Ignoring errors and hoping they will go away

• Deleting code without understanding the purpose

How can you identify and fix errors in your code?

• Guess the solution

• Use debugging tools, read error messages, and test your code

• Ask someone else to fix it

• Ignore the errors

What are loops in coding?

• error in the program

• Character with movement

• A set of instructions or rules to solve a problem or perform a task

• Instruction that need to do it over and over again

How do loops help in writing efficient code?

• By making the code longer and more complicated

• By slowing down the execution of the code

• By causing errors in the code

• By allowing the same set of instructions to be executed multiple times without the need to write them out each time.

What is an algorithm?

• A type of computer hardware

• A set of instructions or rules to solve a problem or perform a task

• A musical instrument

• A form of encryption

Why is it important to understand algorithms in coding?

• To make the code less efficient

• To slow down the coding process

• To write efficient and optimized code, solve complex problems, and improve problem-solving skills.

• To make the code longer and more complicated

How can you create patterns with code?

• By using loops, conditional statements, and mathematical functions

• By using only loops

• By using only one mathematical function

• By using only conditional statements

Give an example of creating a pattern using code.

• Drawing a pattern on paper

• Singing a song to create a pattern

• for example, using nested loops to create a pattern of stars or squares.

• Using a calculator to create a pattern
