Operator overloading problem
hello there
I have a question that I just can't understand it's answer :S
when overloading extraction operator (>>), why do I have to reference the return value?
like this : istream & operator>>(istream&,class&obj);
can anyone explain to me why we write that & before operator>> ?
thanks in advance :)
