reading garbage using ifstream

[nomijigr]

Hi there..I have problem reading data from file...data is written correctly but after reading there is no change in variable where data is saved after reading..
compiler:DEV C++ 5.5.2

  #include<iostream>
#include<fstream>
#include<string>
using namespace std;
int main()
{
	unsigned int write,read=0;
	cin>>write;
        cout<<write;
	ofstream writefile("data.txt");
	writefile<<write;

	ifstream readfile("data.txt");
	if(readfile)
	{
	cout<<read<<endl;
	readfile>>read;
	cout<<read;
    }
    else
    cout<<"unable to open file";
	return 0;
}

if entered number is 5 lets say..5 will be written correctly wth this output
OUTPUT:
5
0
0

Because writefile and readfile refer to the same file, you should close writefile.

#include <iostream>
#include <fstream>
#include <string>

using namespace std; // bad practice that you should unlearn

int main()
{
    unsigned int write, read=0;

    cout << "Give value of `write': ";
    cin >> write;
    cout << "write is " << write << '\n';

    ofstream writefile("data.txt");

    writefile << write;
    writefile.close();

    ifstream readfile("data.txt");

    if (readfile)
    {
        cout << "read is: " << read << '\n';
        readfile >> read;
        cout << "read is: " << read;
    }
    else
        cout << "unable to open file\n";

    return 0;
}
