problem in sorting lists

[Ahmed2]

hello there,

I'm trying to sort a list according to the "length" paramter in ascending order, which represents the third coloumn.
List elements are read from a csv file contains 9 coloumns, I only push 6 coloumns in "futurelist" which is the information i'm intersted in.

//input csv data

1161	19:21	652.6259766	MB	1182	19:42	21	0	0

contents of the list before sorting

1161	652.6259766	1182	21	0	0

What I want

1326	536.0175781	1343	17	0	0
1031	574.1025391	1050	19	0	0

1161	652.6259766	1182	21	0	0

Any body can help me on this, because my code doesn't seem to work. this is my code.

#include <iostream>

using namespace std;

    float length;   //sort elements according to it
    int finishtime;
    int remainingtime;
    int actualfinishtime;
    int delay;
};



// create list
list<FileInfo*>futurelist;



//read from excel file
void FileInput()

for (int t=0;t<5;t++) //read five lines only from the csv file

futurelist.push_back(fi);

}
}
file.close();
}



int main()

  cout <<(*p)->delay<< " ";
    cout<<endl;
p++;
}
cout << "\n\n";

//---------sorting list---------
int temp, i, j, n;
n=futurelist.size();

for(n-1; (n>=1); n--){

    for (int index=0;index<n; index++){
    if(futurelist[index]>futurelist[index+1]) {
    swap(futurelist[index], futurelist[index+1] );
    }
}
}

return 0;
