Task 2
Algorithm Activities 1 - Sequence
Complete these questions in a single file called ‘Algorithm Activities 1’ and submit for
marking.
Remember:
o Title page with your full name, assignment name, date and teachers name
o Use 12 point font size and a plain font for all work
o Use a header/footer which contains student name, date, assignment name
and page numbers as shown in class)
o Clearly set out your work, numbering each question carefully
o Staple all work and place in a sleeve or manilla folder (or similar).
Due date:
For all questions, write the pseudocode and create a flowchart:
Questions:
(Fowler, Ex 4.6, Ques 13)
1
An algorithm to make a phone call is shown below:
Pick up the phone.
Dial number.
Deliver the message.
Hang up the phone.
a Convert the above algorithm into pseudocode. The algorithm should be designed
using a word processor and named with a filename of PHONEPSEU.
b Convert the above algorithm into a flowchart. The algorithm should be designed using
a drawing program and named with a filename of PHONEFLOW.

(Fowler, Ex 4.7, Ques 10-17)
Rearrange into the correct sequence the following steps to sharpen a pencil:
Turn pencil.
Get pencil and sharpener.
Put pencil into sharpener.
Remove pencil from sharpener.
Use a word processor to prepare your answer and name the file as SHARPEN.
Use the steps in question 2 to design an algorithm to sharpen a wooden pencil:
a in pseudocode
b as a flowchart
You can use a word processor for part a, naming your file as SHARPENP, and a
drawing program for part b, naming your file as SHARPENF. (Don’t forget to use
the proper flowchart symbols.)

4
Rearrange into their correct sequence the following steps to make cornflakes for
breakfast:
Pour milk over cornflakes as required.
Get bowl, cornflakes, milk and sugar.
Put sugar over cornflakes as required.
Fill bowl with cornflakes.
5
Using the steps in question 4, design an algorithm to make cornflakes:
a in pseudocode
b as a flowchart
You can use a word processor for part a, naming your file as CORNFLP, and a
drawing program for part b, naming your file as CORNFLF. . (Don’t forget to use
the proper flowchart symbols.)
6
Rearrange into their correct sequence the following steps to wash your hands:
Rinse off soap.
Turn on water.
Dry hands.
Clean hands with soap.
Wet hands.
Turn off water.
7
Using the steps in question 6, design an algorithm to wash your hands:
a in pseudocode
b as a flowchart
You can use a word processor for part a, naming your file as WASHP, and a drawing
program for part b, naming your file as WASHF. . (Don’t forget to use
the proper flowchart symbols.)
You may like to use a word processor and drawing program for the following. If you do, don’t
forget to name your work with appropriate filenames.
8
