Program design (help)

[gerizzel]

i Need 2 design a program that will be able to read the two files of an EWAY Checkpoint (toll for moterway) and customer database, that will be able to produce a statement for each customer who has non-zero balance.
and includes:

Headings of the statement
Customer information: customer’s name, address and customer number.
Column heading: Date, Time, Station, Amount.
All records charged to the customer.
Total amount the customer owned.

plz show me how 2 do this...

read in the toll file, read in the customer file. store the customer's data into a structure. if the customers balance is > 0 then print out the data. what is it that u dont know how to do? we dont do homework here. write some code, when u get stuck then ask a specific question.

fstream InStream("log.txt", ios::in); // open file

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

while (!InStream.eof()) // while not end-of-file:
{
InStream >> tag_number; // input tag number
InStream >> date;
InStream >> time;
InStream >> toll_station;

if (tagNo == tag_number)
{
amountDue = PrintCustomerStatement(tag_number, date, time, toll_station);
// invoke subordinate module
totalAmountDue = totalAmount + amount;
} // end if
} // end while
