Thread: how to notify the EOF?

what should i put in the while condition?

Code:

ifstream file3("idreport.txt");
	char buf1[20],buf2[20];
	while (this is not the END OF FILE)
	{
	file3.getline(buf1,20,' ');
	file3.getline(buf2,20,'\n');
	cout << "buf 1 is" << buf1 << "\n";
	cout << "buf2 is" << buf2 << "\n";
	}
	file3.close();

thank you for helping

Code:

while(!file.eof())
