Well Perhaps I should've been more precise with my reuqest. Basically I'm supposed to anylize the daily maximum and minimum of Temperature, Pressure and Humidity from a file that a user chooses by typing the file name into a prompt after choosing it in a menu. I'm also supposed to find out the maximum daily wind speed as well.
Well Here's my code so far
///
///
///
///
///
/// Program: Weather data processing
/// Created by: Wesley Montgomery
/// This program anlizes weather data accessed from a file and finds the average of Temperature, Humidity, and other facts.
///

///
#include <fstream>
#include <iostream>
#include <string>
#include <cmath>
#include <stdlib.h>
#define MAX_SIZE 4589
using namespace std;
int main()
{
int pressure, temp, windspeed, windchill, dew, heatindx, humidity, rainfall, winddir, avgwindspeed, peakwindspeed, totalrainfall;
bool done; // exit flag
char selection; //Menu Selection
string file; // Name of datafile
ifstream weatherfile; //datafile stream
// Initialize exit flag
done = false;
while (!done)
{
// Output menu list
cout << "\n\n";
cout << "************************\n\n";
cout << " Weather Data Analysis: \n";
cout << " 1) Select Data File to be loaded\n";
cout << " 2) Daily Min/max of Temp,Pressure and humidity\n";
cout << " 3) Daily Max Wind Speed\n";
cout << " 4) Avg Pressure, Humidity, and Windspeed for rainy days\n";
cout << " 5) Total Daily Rainfall\n";
cout << " 6) Exit Program\n";
cout << "************************\n\n";
// Input data
cout << "Selection -> ";
cin >> selection;
cout << "\n\n";
// Process input
if (selection=='1')
{
cout << "Insert Data file:";
cin >> file;
weatherfile.open (file.c_str(), ios::in);
cout << "\n\n";
}
else if (selection=='2')
{
while (!weatherfile.eof())
{
}
}
else if (selection=='3')
{
while (!weatherfile.eof())
{
}
}
else if (selection=='4')
{
while (!weatherfile.eof())
{
if (rainfall > 0)
{
}
}
}
else if (selection=='5')
{
while (!weatherfile.eof())
{
}
}
else if (selection=='6')
{
cout << "Goodbye. Thank you for using my program.\n\n";
done = true; // flag for exit
}
else
{
cout << "** Invalid Selection. **\n\n";
}
} // end of while loop
return (0);
}
And here's an example of the file it's supposed to open.

And Well I'm also getting errors with this code of mine that mostly say 'unreferenced local variable even though they are there in the int list at the top. I tried find some solutions in my book, but it didn't help that much. I also tried to find information on the internet but I didn't have any luck there as well.
So could someone help me with this little problem?
