I am using Turbo C++ for Windows. I've got a linker error as follows:
Linker Error:Undefined symbol operator << [opstream near&, double] in
But opstream does has a friend operator << for this as I see it from
friend Ropstream operator << (Ropstream PS, double d); // from online help.
Is this "<<" different from the previous "<<"? Anything wrong here?
Ropstream here can read and write int and char, but doesn't work to double
and float. I can't figure out the difference.
Any advice will be greatly appreciated.
