hi guys,
need help urgently on extracting data from text file and compute it.
i'm suppose to sum up the highest temp and divide them by 7 to get an average decimal.
only display data on compiler without calculating the average sum.
ok here is my code.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
class Weather
{
public:
Weather() {};
void getweek3htemp(Weather myWeather[]);
void viewhtemp(double);
static int numWeather;
void setInfo(int,double,double,double,double,string);
private:
int day;
double htemp;
double ihtemp;
double wkavg;
double ltemp;
double humdity;
double rain;
string condition;
};
int Weather::numWeather = 0;
void readFile(Weather[]);
void Weather::setInfo(int inday, double inltemp,double inhtemp,double inhumdity,double inrain,string incondition )
{
day = inday;
ltemp = inltemp;
htemp=inhtemp;
humdity=inhumdity;
rain=inrain;
condition=incondition;
}
void Weather::viewhtemp(double)
{
cout << "Highest Temperature: " << htemp << endl;
cout<< wkavg<<endl;
wkavg=wkavg+htemp;
}
void Weather::getweek3htemp(Weather myWeather[])
{
for(day=14;day<21;day++)
myWeather[day].viewhtemp(htemp);
wkavg=wkavg/7;
cout << "average of the week"<< wkavg<< endl;
}
void readweek3(Weather[]);
int main(void)
{
Weather myWeather[500];
cout << "Reading Statistics from file" << endl;
readFile(myWeather);
cout << "Display week 3 information" << endl;
readweek3(myWeather);
system("pause");
return 0;
}
void readweek3(Weather myWeather[])
{
ifstream fin;
char filename[50];
cout << "Enter filename (including .txt):" << endl;
cin>>filename;
fin.open(filename);
if (!fin.good())
{
cout << "File not found" << endl;
exit(1);
}
while(!fin.eof())
{
int num =-1;
myWeather[num].getweek3htemp(myWeather);
break;
}
fin.close();
system("pause");
}
void readFile(Weather myWeather[])
{
int day,num;
double ltemp,htemp,humdity,rain;
string condition;
ifstream fin;
char filename[50];
cout << "Enter filename (including .txt):" << endl;
cin>>filename;
fin.open(filename);
if (!fin.good())
{
cout << "File not found" << endl;
exit(1);
}
while(!fin.eof())
{
fin >> day >> ltemp >> htemp >> humdity >> rain >> condition;
num = Weather::numWeather;
myWeather[num].setInfo(day,ltemp,htemp,humdity,rain,condition);
Weather::numWeather++;
}
fin.close();
system("pause");
}
