multimap

I have 2 input files xx.txt & yy.txt

contents of xx.txt are as follows
Aardenburg,,34394,512775,4527
Aardenburg,,30000,500000,4527
fields are city,cu,x,y,poco

contents of yy.txt are as follows

4527 AA,AARDENBURG
4527 AB,AARDENBURG
4553 AA,PHILIPPINE
4553 AB,PHILIPPINE
4555 xx,girija

fields are poco & city.

I want to match 4 digit poco & city of yy.txt with poco & city of xx.txt.if they are matched 7digit poco of yy.txt should be appennded.output should be as follows.

Aardenburg,,34394,512775,4527,@4527 AA@4527 AB
Aardenburg,,30000,500000,4527,@4527 AA@4527 AB

the coding is as follows

      {
            cout<<it->first<<"\n";
            cout<<it->second<<"\n";

      }

}

but it prints the o/p as follows.

Aardenburg,,34394,512775,4527,@4527 AA@4527 AB

can anyone giude me?

20 points is not going to get you far ...
I understand that your problem is that the multimap is not containing all records, so check the place where you insert these records and print a trace just before the insert and afterwards check if it was inserted.

I suggest that first you use C++ as you should and encapsulate reading from each file.
Then apply the processes to the adecuate object.
It will be much easier to debug and maintain.

>> 20 points is not going to get you far ...

I learned from one of your previous questions that could not give more points as you have no more left. I suppose, you know that you could get more points if you spend some money to EE.. Also, you already spend a lot of points not getting a final solution to your task. The reason for this is your input files that always are changing from question to question and most of your problems you only got because your code doesn't reflect these changes. If you had given us a good spec, two input file definitions that would hold longer than a day and say 300 points some weeks before, you would have now a better solution and still points left.

Regards, Alex

BTW, if you would post here a final spec, i would show you a much better coding than that you have til now. And i don't need more points... ;-)
