Operator Overloading of array output

[mouse163]

Hi all...
I have a question regarding overloading of the << operator.
I am using it as a friend function of a class in order to print out
the private data of each object of the class when created.
It works beautifully when i create a single object, however...
if I attempt to create an array of objects of the class a cout <<
statement of each object simply gives me the output of the memory address.
I can't seem to find any examples of this behavior, in addition
I've dynamically allocated my array, don't know if this has cause even more problems.
The class and member function (including the firiend to overload is below) I also want to overload the >> operator to load data into the class buuut...am alot farther away from that thought process.
Thanks so much!

try, i'm not sure, but i think this is right:

cout << *bseat[i] << endl;

also, you're istream should be:

istream & operator >> (istream & input,  Seat &seat_o ) //not << operator

actually i was using a reference parameter and calling a pointer once i changed that..things were better the << operator instead of >> was an accidental typo - i hadn't attempted that function yet
thanks alpha
