basic_streambuf::sgetc
Returns current element without changing position in the stream.
int_type sgetc( );
Return Value
The current element.
Remarks
If a read position is available, the member function returns traits_type::to_int_type(*gptr). Otherwise, it returns underflow.

cout << i << endl;
i = myfile.rdbuf( )->sgetc( );
cout << i << endl;
