    inf.close();

    cin.get();
    return 0;
}

can you tell me why do i get a wrong output when I try to read the file created
ouput is like :

Enter item: soap
Enter item cost: 25
written to file item.txt
soap
255 //I am getting an extra 5 here.why?
reads from file item.txt

Because you are using .eof to control your loop. See this. feof() is exactly the same.
