Deakin College SIT105 Thinking Tech & Design Major Assignment

This assignment solution for Deakin College's SIT105 Thinking Technology and Design course includes detailed answers to four questions. The solutions utilize IPO charts and pseudo code to address problems related to mobile usage, zoo ticket price calculation, and rain forecasting. The document provides algorithms for each scenario, demonstrating the use of sequence, selection, and iterative constructs. The solution is designed to help students understand the concepts behind programming and problem-solving. Desklib offers a wealth of similar resources, including past papers and solved assignments, to support students in their academic endeavors.

Q no 1 Answer:
IPO Chart:
Input Process Output
Phone number Get phone number from user Country name
Extract the country code from
the phone number
Identify the country using the
country code
Display the country name
Q no 2 Answer:
Pseudo code:
Mobile_Usage //Main algorithm for determining the mobile use and display warning message
Get mobile_usage_in_min
//Checking if mobile_usage_in_min is less than 1 hour (Since 1 hour is equal to 60 minutes)
IF mobile_usage_in_min < 60 THEN
DISPLAY "Usage is acceptable"
//Checking if mobile_usage_in_min is greater than or equal to 1 hour and less than 2 hours
ELSE IF 60 <= mobile_usage_in_min && mobile_usage_in_min < 120
DISPLAY "Mediocre Usage"
//Checking if mobile_usage_in_min greater than 2 hours or not
ELSE IF 120 < mobile_usage_in_min
DISPLAY "Warning, using your phone more than 2 hours per day can affect your health"
