	I am new to c++, though I've been using c for a long time.
In C, one can use command line parameters to specify whether input
is taken from a input file or from the std. terminal. one would
typically do it as:
main ( int argc, char *argv [])
{
	FILE *fin, *fout, *fopen ();

	if (argc == 1)
	{
		fin = stdin;
		fout = stdout;
	}
	else
	{
		fin = fopen (*++argv, "r");
		fout = fopen (*++argv, "w");
	}
	.
	.
	then to read input
	fscanf (fin, "...", ..);
}

I donot want to use fscanf or fprintf in c++. So is there a
similar way (or better way) of doing it using
'cout' and 'cin' in c++.
please send me email as i don't read this very often.

thanks
raghu
