Thread: c++ file IO

Code:

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

int main()
{
     char c;
     
     ofstream fout("O.TXT",ios::out|ios::binary);
     fout << "C++Programming";
     fout.close();
     
     ifstream fin("O.TXT",ios::in|ios::binary); 
     while( !fin.eof() )
     {
         fin.get(c);
         if( !fin.eof() )
             cout << c;
     }
     fin.seekg(0,ios::beg);
          
     fin.get(c);
     cout << ' ' << c << endl; 
            
     fin.close();

     system("PAUSE");
     return 0;
}

The code must give the output "C++Programming C". But the output i am getting is "C++Programming g". In many cases i have seen when i have forwarded the file pointer , the characters can be well read but when the pointer is brought back the desired characters cannot be read.

Tried on VC++ 6.0 and DEV C++ 4.9.9.0

Because it still thinks you're at eof, so the next get call doesn't actually update c, and it's left with the last character which was successfully read.

fin.clear(); // make the eof condition go away
fin.seekg(0,ios::beg); // back to start

Now I get
$ ./a.out
C++Programming C
