Answer 1

anyone to throw some light on this??

Let me describe some more detail...

I/o operators can only be overloaded as friend function and it's not possible to overload as member function... Why?? because overloaded member function must have left operand as class object, but overloaded o operator must have return type as ofstream copy object... This ensures proper behaviour with cout...

Same way, assignment operatior can be only overloaded as member function and not possible as friend function... Any logic for this ????????
