Project 5

Extend the functionality of project 4 to

- incorporate a history of the past 4 weather measurements

- update the user menu to include

- printing the current weather

- printing the weather history (from most recent to oldest)

Use a text-driven menu to present the choices for actions to the user

C++ code:

#include

#include

using namespace std;

int main()

{

string name;

int choice;

double temperature, windSpeed;

string windDirection;

bool initialized = false;

//Have teh user provide a name for the weather station upon entry

cout << "Enter the name of weather station: ";

getline(cin, name);

//control loop to perform various actions

while(true)

{

cout << "1. Input a complete weather reading." << " ";

cout << "2. Print the current weather." << " ";

cout << "3. Exit the program." << " ";

cout << "Enter your choice: ";

cin >> choice;

//switch based on choice

switch(choice)

{

case 1:

do

{

cout << "Enter the temperature (a value >= 0): ";

cin >> temperature;

}while(temperature < 0);

//get correct wind speed

do

{

cout << "Enter the wind speed (a value >= 0): ";

cin >> windSpeed;

}while(windSpeed < 0);

//get correct wind direction

do

{

cout << "Enter the wind direction (North, South, East or West): ";

cin >> windDirection;

}while(windDirection != "North" && windDirection != "South"

&& windDirection != "East" && windDirection != "West");

initialized = true;

if(initialized)

{

cout << "*****" << name << "******" << endl;

cout << "Temperature: " << temperature << endl;

cout << "Wind Speed: " << windSpeed << endl;

cout << "Wind Direction: " << windDirection << endl;

}

break;

case 2:

if(!initialized)

{

cout << "Please enter the details before asking to print." << endl;

}

else

{

cout << "*****" << name << "******" << endl;

cout << "Temperature: " << temperature << endl;

cout << "Wind Speed: " << windSpeed << endl;

cout << "Wind Direction: " << windDirection << endl;

}

break;

case 3:

return 0; //stop execution

default:

cout << "Invalid choice. Please follow the menu." << endl;

}

}

}
