i have file which is contain of name, ID ,Marks and i want to sort it ascending by the Marks

and this is my code
Code:

#include <iostream.h>
#include <fstream.h>

struct sort
{
        char names [20];
        long ids;
        int marks;
}result;
 main()
{
        int temp;
sort nafek [5],index[5];
fstream  file;
file.open("data.dat",ios::in);
for (int i=0;i<3;i++)
{

file>>nafek [i].ids>>nafek[i].marks>>nafek[i].names;



}
for (i=0;i<3;i++)
{
        for (int j=i+1;j<=3;j++)
        {
                if (nafek[j].marks<nafek[i].marks)
                {
                        temp=nafek[i].marks;
                        nafek[i].marks=nafek[j].marks;
                        nafek[j].marks=temp;
        }}
}
for (i=0;i<3;i++)
{

cout<<nafek[i].marks<<" "<< nafek[i].names<<nafek[i].ids<<'/n';
file.close();
}
        return 0;
