HOMEWORK 3 Computational thinking

Q1. What is a Pseudocode?

• Identifies essential details
• Disregards non-essential information
• A set of instructions similar to a computer program, but without the strict rules.

Q2. What are Flowcharts?

• Just blocks with no meaning.
• A set of instructions shown as a visual diagram.
• Odd charts

Q3. What are the two main ways that algorithms can be designed?

• In pseudocode or as a flowchart
• Images or videos
• By hardware or software

Q4. What is the symbol for a decision in a flowchart?

• A square
• A parallelogram
• A circle
• A diamond

Q5. Which of these is the correct symbol for a process in a flowchart?

• A diamond
• A rectangle
• A parallelogram

Q6. When can algorithms be used?

• To design a solution to any problem
• Only with computers
• For programming

Q7. hat is important to remember when designing an algorithm?

• the instructions are in the correct order
• whether to use a flowchart or pseudocode
• that it must be easy to read

Q8. To repeat a task number of times, we use

• conditional statement
• input statement
• loop statement
• output statement

Q9. On a flowchart, a decision will always have:

• Three exit arrows
• One exit arrow
• Four exit arrows
• Two exit arrows

Q10. When planning an algorithm using flowcharts, you can use any symbols you'd like.

• True
• False
