Deakin College SIT105 Thinking Technology and Design Major Assignment

This document presents solutions to a SIT105 assignment from Deakin College, covering concepts in Thinking Technology and Design. The solution includes IPO charts and pseudo-code for several programming problems. The first problem involves creating an IPO chart to process phone numbers. The second problem uses pseudo-code to analyze mobile phone usage. The third problem utilizes pseudo-code to calculate ticket prices for families. The fourth problem uses pseudo-code to determine the chance of rain based on temperature and humidity. The assignment emphasizes algorithm design, selection, sequence, and modularization, providing a comprehensive understanding of programming principles, as required in the assignment brief.

including Country
Code
Processing Item:
Array of Country Code
Array of Corresponding Country Name
Country Name
2. Solution:
Pseudo Code:
// Get the usage of mobile phones per day in minutes
Read mobile_usage_in_minutes
// Convert the mobile phones usage from minutes to hours
Set mobile_usage_in_hours to mobile_usage_in_minutes/60
// Check if the mobile usage is less than 1 hour
If (mobile_usage_in_hours < 1)
// Display the Message - “Usage is acceptable”
Write “Usage is acceptable”
// Check if the mobile usage is between 1 hour and 2 hours
Else if(mobile_usage_in_hours <= 2)
// Display the Message - “Mediocre Usage”
Write “Mediocre Usage”
// if the mobile usage is more than 2 hours
Else
// Display the Warning Message
Write “Warning, using your phone more than 2 hours per day can affect your
health”
3. Solution:
Pseudo Code:
// This module helps to write the family name and its corresponding ticket price
Module WriteToFile (familyNameArray, totalTicketPriceArray)
// open the file “Ticket_Prtice.xlsx” to write the contents
file = Open File named “Ticket_Prtice.xlsx” in Write Mode
//Write the header to the file
WriteLine (file, “Family Name”, “Total Ticket Price”)
// loop for each family in familyNameArray
For index = 0 to len(familyNameArray)
// Write the family name and its corresponding ticket price
WriteLine (file, familyNameArray(index), “$”+totalTicketPriceArray(index))
End For

// close the file
Close file
End Module
// This module helps to determine the cost of the ticket
Module getCost ( noOfTickets, price)
// compute the cost of the ticket
cost = noOfTickets*price
// return the cost of the ticket
return cost
End Module
Module Main
// create array to store the family names
Create String Array named familyNameArray
// create array to store the ticket price
Create String Array named totalTicketPriceArray
Set index to 0
// open the file “Family_Info.xlsx” to read its contents
file = Open File named “Family_Info.xlsx” in Read Mode
// read the header line
Read header Line
// read the file line by line until EOF
While file not EOF
// read the line and split the data by comma
data=Read Line and split
// determine the name of the family name
familyNameArray [index] = data[0]
// determine the cost of adult tickets
Call getCost(data[1],37)  adultTicketCost
// determine the cost of teenager tickets
Call getCost(data[2],25)  teenagerTicketCost
// determine the cost of children tickets
Call getCost(data[3],18)  childrenTicketCost
//calculate the cost of all adult, teenager and childer tickets

totalTicketPriceArray[index] = adultTicketCost + teenagerTicketCost +
childrenTicketCost
// increment index by 1
index += 1
End While
// Call WriteToFile function to write the content of family name and total ticket price
Call WriteToFile (familyNameArray, totalTicketPriceArray)
// close the file
Close file
End Module
4. Solution:
Pseudo Code:
// This module is used to check if the temperature value is valid
Module isValidTemperature(temperature)
// Check if temperature is in specified range -20 and 55
If (temperature < -20 || temperature > 55)
Return False
Return True
End Module
// This module is used to check if the humidity value is valid
Module isValidHumidity (humidity)
// Check if humidity is positive integer equal or less than 100
If (humidity <= 0 || humidity > 100)
Return False
Return True
End Module
// This module determines the chance of rain based on temperature and humidity value
Module determineChanceOfRain (temperature, humidity)
// Checks if the temperature is Less than 0 and Humidity is Less than 20%
If (temperature < 0 and humidity < 20)
Write “Chance of Rain: 0%”
// Checks if the temperature is Between 0 and 15 and Humidity is Between 20% to 40%
Else If (temperature >=0 and temperature <=15 and humidity >= 20 and humidity <= 40)
Write “Chance of Rain: 20%”
// Checks if the temperature is Between 15 and 30 and Humidity is Between 40% to 60%

Else If (temperature >=15 and temperature <=30 and humidity >= 40 and humidity <=
60)
Write “Chance of Rain: 50%”
// Checks if the temperature is More than 30 and Humidity is Between 60% to 80%
Else If (temperature > 30 and humidity >= 60 and humidity <= 80)
Write “Chance of Rain: 75%”
// Checks if the temperature is More than 30 and Humidity is More than 80%
Else If (temperature > 30 and humidity > 80)
Write “Chance of Rain: 90%”
End Module
Module main()
// Get temperature in Celsius from User
Read temperature
// Get humidity from User
Read humidity
// Check if the temperature is valid by calling the Module isValidTemperature
Call isValidTemperature(temperature)  isValidTemp
// If the temperature is not valid
If (isValidTemp is False)
{
// Display Temperature Error message
Write “Temperature should be between -20 and 55”
}
Else
{
// Check if the humidity is valid by calling the Module isValidHumid
Call isValidHumidity (humidity)  isValidHumid
// if the humidity is not valid
If (isValidHumid is False)
{
// Display Humidity Error message
Write “Humidity should be a positive integer equal or less than 100”
}
Else
{
// Call the module determineChanceOfRain to determine chance of rain in
percentage

Call determineChanceOfRain (temperature, humidity)
}
}
End Module
