Question

/* Problem description: The text file DJI.txt contains the information of a stock market index --
    Dow Jones Industrial Average Index (DJI for short) -- for a continuous time
    in year 2008. Each line contains the date and the DJI's value on that day.
    For the format of the file, please view DJI.txt.
    
    Please write a program that reads DJI values stored in the data file DJI.txt,
    and finds out the date with highest DJI value during this period stored in the file.
*/

#include <string>
#include <iostream>
#include <fstream>
using namespace std;

int main( )
{
    const string    inputFile = "/var/www/html/programs2/2170_1_5/dataFiles/DJI.txt";
    ifstream          ifs;        //an input file stream
    
    int             day;        //Today's day
    int             maxDay;        //The day of the date with max. DJI
    string        month;        //Today's month
    string        maxMonth;    //The month of the date with max. DJI
    double      maxDJI;        //The max. DJI value got so far.
    double       dji;        //Today's DJI

    ifs.open( inputFile.c_str() );    //open the file
    
    Please write a program that reads DJI value from the file opened above, and find out the date with highest DJI value during this period.
    ifs.close();    //close the input file
    
    cout << "DJI is highest on " << maxMonth << " " << maxDay << " with " << maxDJI << endl;          

    return 0;
}

Explanation / Answer

//put this code in blank space

string temp;

ifs>>maxMonth>>maxDay>>temp>>maxDJI;

while(ifs>>month>>day>>temp>>dji)

{

if(dji>=maxDJI)

{

maxMonth=month;

maxDay=day;

maxDJI =dji;

}

}
