This program is supposed to read files and write them. I took the file open checks out because they kept causing errors. The problem is that the files open like they are supposed to and the names are correct but nothing is on any of the text screens. Do you know what is wrong?

#include<iostream>
#include<fstream>
#include<cstdlib>
#include<iomanip>
using namespace std;
int main()
{
    ifstream in_stream; // reads itemlist.txt
    ofstream out_stream1; // writes in items.txt
    ifstream in_stream2; // reads pricelist.txt
    ofstream out_stream3;// writes in plist.txt
    ifstream in_stream4;// read recipt.txt
    ofstream out_stream5;// write display.txt

    float price='  ',curr_total=0.0;
    int itemnum='  ', wrong=0;
    char next;

    in_stream.open("ITEMLIST.txt", ios::in); // list of avaliable items
    out_stream1.open("listWititems.txt", ios::out); // list of avaliable items           
    in_stream2.open("PRICELIST.txt", ios::in);           
    out_stream3.open("listWitdollars.txt", ios::out);               
    in_stream4.open("display.txt", ios::in);    
    out_stream5.open("showitems.txt", ios::out);

  in_stream.close(); // closing files.
  out_stream1.close();
  in_stream2.close();
  out_stream3.close();
  in_stream4.close();
  out_stream5.close();
  system("pause");

    in_stream.setf(ios::fixed);
    while(in_stream.eof())
    {
        in_stream >> itemnum;
        cin.clear();
        cin >> next;
    }

    out_stream1.setf(ios::fixed);
    while (out_stream1.eof())
    {
        out_stream1 << itemnum;
        cin.clear();
        cin >> next;
    }

    in_stream2.setf(ios::fixed);
    in_stream2.setf(ios::showpoint);
    in_stream2.precision(2);
    while((price== (price*1.00)) && (itemnum == (itemnum*1)))
         {
             while (in_stream2 >> itemnum >> price) // gets itemnum and price
             {
                 while (in_stream2.eof())  // reads file to end of file
                 {
                 in_stream2 >> itemnum;
                in_stream2 >> price;
                price++;
                curr_total= price++;
                in_stream2 >> curr_total;
                cin.clear();  // allows more reading
                cin >> next;
                }

            }
        }

    out_stream3.setf(ios::fixed);
    out_stream3.setf(ios::showpoint);
    out_stream3.precision(2);
    while((price== (price*1.00)) && (itemnum == (itemnum*1)))
        {
         while (out_stream3 << itemnum << price)
             {
                 while (out_stream3.eof())  // reads file to end of file
                 {
                 out_stream3 << itemnum;
                 out_stream3 << price;
                 price++;
                 curr_total= price++;
                 out_stream3 << curr_total;
                 cin.clear();  // allows more reading
                 cin >> next;
                 }
                return itemnum, price;
            }
        }

    in_stream4.setf(ios::fixed);
    in_stream4.setf(ios::showpoint);
    in_stream4.precision(2);
    while ( in_stream4.eof())
    {
        in_stream4 >> itemnum >> price >> curr_total;
        cin.clear();
        cin >> next;
    }

    out_stream5.setf(ios::fixed);
    out_stream5.setf(ios::showpoint);
    out_stream5.precision(2);
    out_stream5 <<setw(5)<< " itemnum " <<setw(5)<<" price "<<setw(5)<<" curr_total " <<endl; // sends items and prices to receipt.txt 
    out_stream5 << setw(5) <<  itemnum << setw(5) <<price << setw(5)<< curr_total; // sends items and prices to receipt.txt 
    out_stream5 << " You have a total of " << wrong++ << " errors " << endl;
