Programming

Hi All,

I am trying to read data from two files and then compare them and only print the records on the screen that have a same ID.i.e TAGNO =CUSTOMERNO
For Eg
My Input Files are (a) Transaction (b) Customer detail
The data in file a is like:
TagNo Date Time Station
4092191 03/08/04 23:49:08 A
4749038 05/04/04 14:16:35 B
4092191 04/13/04 23:42:08 C
4092191 04/13/04 23:47:18 D
3873242 05/16/04 02:40:59 B

Data in File B
CustomerNo Initila Surname Street Suburb State Postcode
4092191 T Menon Evan Penrith NSW 2750
3873242 R Merritt Bent Mosman NSW 2090

Additional Criteria is , if the Grade is A the charges 2.20, B- 2.80, C-3.30 & D -3.80.

The expected output is :
Customer No:
Customer Name:
Address:
details of the transactions:
=======================
Customer No Date Time Grade Charges

Below is the code I am trying:

#include <stdlib.h>
#include <fstream.h>
#include <cstring.h>
#include <stdlib.h>
#include <iomanip.h>
void main()
{
string Dt,Tm;
float Charges;
string TagNumber, CustomerNo;
char Station;
string Intial,Surname,StreetNo,StreetName;
//char Intial[2],Surname[10],StreetNo[3],StreetName[20];
char StreetType[20],Surburban[20],State[20],Postcode[5];
float calc_charges( string Station );


//open the files
ifstream InStream("a:\trans.txt",ios::in), InStream1("a:\customer.txt",ios::in);

// check for Instream File, if the file doesn't exist, print error message
if (InStream.fail()) // check for success
{
cerr << "\n Unable to open 'data.txt'!\n";
exit (-1); //
} // end if

if (InStream1.fail()) // check for success
{
cerr << "\n Unable to open 'data.txt'!\n";
exit (-1); //
} // end if


while (!InStream.eof()) // while not end-of-file:
{

InStream >> TagNumber>>Dt>>Tm>>Station;
Charges = calc_charges( Station );

} //while(!input.eof());

//open the customer detail file

// ifstream InStream1("a:\customer.txt",ios::in);

// if the file doesn't exist, print error message
if (InStream1.fail()) // check for success
{
cerr << "\n Unable to open 'customer.txt'!\n";
exit (-1); //
} // end if


while (!InStream1.eof()) // while not end-of-file:
{

InStream1 >> CustomerNo>>Intial >> Surname>> StreetNo>> StreetName
>> StreetType >> Surburban>> State>> Postcode;


cout << "\n Customer Name : " << Intial <<" " << Surname <<endl;
cout << " Address : " <<StreetNo << " "<<StreetName << " " <<StreetType<<endl;
cout << Surburban << " " << State << " " << Postcode <<endl;
cout << " Customer Number : " << CustomerNo <<endl;
cout <<endl;
cout << CustomerNo << "|" << Dt << "|" << Tm << "|" <<Station
<< " " << setw(4) << setiosflags(ios::fixed) << setprecision(2)
<< Charges << endl;
}
}


// function definition
float calc_charges( string Station )
{
float the_Charge;
if (Station == 'A')
the_Charge = 2.20;
else if (Station == 'B')
the_Charge = 2.80;
else if (Station == 'C')
the_Charge = 3.30;
else if (Station == 'D')
the_Charge = 3.80;

return the_Charge;
}

==================
The output that it gives is not correct.

Can someone Please help me out.

Thanks
