eof problem c++

i am using Dev C++ on windows xp

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

int main ()
{
    st开发者_JS百科ring STRING;
    ifstream infile;
    infile.open ("sample.txt");
        while(!infile.eof)
        {
            getline(infile,STRING); 
            cout<<STRING; 
        }
    infile.close();

    return 0;
}

this codes gives the following error

C:\C++\read.cpp: In function `int main()':

C:\C++\read.cpp:11: error: could not convert `infile.std::basic_ios<_CharT, _Traits>::eof [with _CharT = char, _Traits = std::char_traits<char>]' to `bool'
C:\C++\read.cpp:11: error: in argument to unary !

i am not sure what is wrong here i cant compile the code please help

If you change your loop to

  while(getline(infile,STRING))
  {
     cout<<STRING; 
  }

you avoid the possibility of reading the last value twice (see this SO post).

std::ifstream::eof is a function that returns a bool. Thsu you have to call it like

infile.eof()

You forgot the () after the eof.
