binary file

can someone pls tell me what is wrong with my program

Code:

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
	fstream rfile;
	rfile.open("ITEMS.DAT", ios::in|ios::out);
	if(!rfile)
	{
		cout<<"error\n.";
		exit(1);
	}
	int c=0;
	cout<<"Enter c\n";
	cin>>c;
	cin.get();
	rfile.seekp(0, ios::end);
	rfile.write( (char*) (&c), sizeof(int) )<<flush;
	rfile.seekg(0, ios::beg);
	while (!rfile.eof())
	{
		rfile.read( (char*) (&c), sizeof(int));
		cout<<"c is:"<<c<<endl;
	}
	rfile.clear();
	rfile.close();
	return 0;
}

// the output is this

//enter c

// c is:2
// c is:2

question: why are there two outputs of 2 even though the file is clean and i only enter one 2?

thank u salem you have been a great help
