Introduction to Coding

What is the purpose of coding?

• To play games

• To create instructions that computers can understand

• To design websites

• To save files

Which of the following best describes an algorithm?

• A program on the computer

• A set of steps to complete a task

• A coding language

• A type of data

What is a flowchart used for in coding?

• To draw pictures

• To represent an algorithm visually

• To play sounds

• To write stories

Why is it useful to write an algorithm before starting to code?

• To make coding easier by organizing steps

• To make the code more confusing

• To make it look impressive

• To change the language of coding

Identify the error in this algorithm for calculating 10 x 3 on a calculator: Step 1: Enter 10 Step 2: Press the + button Step 3: Enter 3 Step 4: Press =

• Step 1

• Step 2

• Step 3

• Step 4

What should you do if your code is not working correctly?

• Check for mistakes and fix them (debugging)

• Delete the code

• Write a new code without checking

• Ignore the errors

While debugging, you realize the calculator code shows "multiplication" instead of "addition." What's the most likely cause?

• The formula or symbol is incorrect

• The calculator is broken

• You need to restart the calculator

• You need to reinstall the calculator program

What should you do if you find a mistake in your algorithm?

• Correct the steps clearly and logically

• Skip that part and continue

• Ask someone else to complete it

• Start coding without fixing it

In a flowchart for brushing your teeth, which step is a decision?

• Pick up the toothbrush

• Check if the toothbrush is wet

• Rinse with water

• Add toothpaste

What could happen if you don't debug your code?

• The code will run perfectly

• The code may show errors or not work at all

• It will run faster

• The code will look different
