fstream - eof problem c++

i am using Dev C++ on windows xp

#include 
#include 
#include 
using namespace std;

int main ()
{
    string STRING;
    ifstream infile;

    infile.open ("sample.txt");
        while(!infile.eof)
        {
            getline(infile,STRING); 
            cout<        }
    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]' 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

Answer

If you change your loop to

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

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