I am to use two input files to create three other output files of specific formatting.

I need to use structs and arrays..I am lost can someone help point me in the right direction?

If the contents of lastweek.txt is (input)

1275 greeting_cards 42 0 1.95 2.75
2907 note_cards 30 0 6.47 7.95
4321 calendars 9 30 6.45 8.57
5140 pens 22 0 2.63 3.19
9673 candles 31 0 3.19 5.85

and the contents of transaction.txt is (input)

11/29/2010 S 2907 1
11/29/2010 S 9673 4
11/30/2010 A 4321 30
11/31/2010 S 9673 12 
12/01/2010 N 5789 wind_chimes 13.54 17.83
12/02/2010 S 5140 5

Then the contents of thisweek.txt is (output)

1275 greeting_cards 42 0 1.95 2.75
2907 note_cards 29 0 6.47 7.95
4321 calendars 39 0 6.45 8.57
5140 pens 17 30 2.63 3.19
9673 candles 15 30 3.19 5.85 
5789 wind_chimes 0 30 13.54 17.83

the contents of sales.txt is (output)

   DATE      ITEM NO.    ITEM        QTY    PRICE     TOTAL
11/29/2010    2907     note_cards     1      7.95      7.95
11/29/2010    9673     candles        4      5.85     23.40 
11/31/2010    9673     candles       12      5.85     70.20
12/02/2010    5140     pens           5      3.19     15.95
                                            TOTAL    117.50

and the contents of orders.txt is (output)

   DATE      ITEM NO.    ITEM        QTY    PRICE     TOTAL
11/31/2010     9673    candles        30     3.19     95.70
12/01/2010     5789    wind_chimes    30    13.54    406.20
12/02/2010     5140    pens           30     2.63     78.90
                                            TOTAL    580.80

Please press the code button before you paste your code. Please explain your problem better. What does your program do to the data before it writes it into other files?

How can I read in a text file so that I can get any piece of that string of various data types?

#include <sstream>
#include <iomanip>
#include <iostream>
#include <fstream>
#include <string>
using namespace std;


int main () {

    string line;
    string data[6];
    int datacounter = 0;
    string substr = "";
    ifstream lastfile;
    lastfile.open("lastweek.txt"); 



    ifstream myfile;
    myfile.open ("transaction.txt");

  ofstream thisfile;
  thisfile.open ("thisweek.txt");


      getline(lastfile,line);


  for (int i = 0; i< line.length(); i++)
  {
      if (line.at(i) == ' ')
      {
            data[datacounter] = substr;
            datacounter ++;
            substr = "";
      }
      else
      {
          substr = substr + line.at(i);
      }
  }

  //print outs each substring
  for (int j = 0; j< 6; j++)
  {
      cout << data[j]<<" ";
  }
  cout << endl;

  datacounter = 0;
}
