Unable to open file n C++

C++

hi
I'm trying to write/read from a file in c++. The function which writes to a file is as follows:

const char * EncQR = Extract_ClientPublicKey_Encrypt_QRcode(str, ClientCert_String);

ofstream myfile1;
myfile1.open("ram.txt");
if (myfile1.is_open())
  {
	   myfile1 <<EncQR<<"\n";
  }
else
   cout<<"Unable to open file";

The previous code works fine, and write into a txt file. But the problem is with the next function, which tries to read from a file:

int _tmain(int argc, _TCHAR* argv[])
{
   string line;
  // reading a text file
  ifstream myfile1("ram.txt");
  if (myfile1.is_open())
  {
   while(! myfile1.eof()) {
			getline(myfile1, line);
			std::cout << line << "\n\n";}
  }

  else cout << "Unable to open file";
  getch();
  myfile1.close();
  return 0;
}

Where i keep getting "Unable to open file". I've tried another file consisting of a single line, and it was working. but with the "ram.txt" file, which consists of multiple lines, it doesn't work.
I even tried to copy the file into the directory in which my project is located, and still, didnt work.

Need help pleeeeease

Regards.
