Writing Algorithms

Question 1

What is pseudocode

Answer 1

Not an actual programming language, but it should follow a similar structure and read like one. It shows an algorithms steps without worrying about the finer details of any particular programming language.

Question 2

Do you need to be careful about when writing pseudocode

Answer 2

Making sure it isn’t too vague. Even though the pseudocode isn’t a formal programming language you still need to make sure it’s readable, easy to interpret and not too vague.

Question 3

How can algorithms be shown?

Answer 3

Using flow diagrams

Question 4

Play diagrams use different ——— for different commands?

Answer 4

Boxes

Question 5

What box is the beginning and the end of the algorithm put in?

Answer 5

A box with rounded corners

Question 6

Answer 6

Question 7

General instructions, processes and calculations go into what box?

A diamond box

Question 9

What is a subroutine?

Answer 9

Question 10
