Pseudo Code Solutions

This document provides pseudo code solutions for various problems. It includes solutions for checking phone number country code, determining mobile phone usage, writing family names and ticket prices, and determining chance of rain based on temperature and humidity.

DOCUMENTATION
1. Solution:
IPO Chart
Input Processing Output
Phone Number
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
