//delete ob1;

return 0;
}


$ g++ total.cpp
total.cpp: In function `int main(int, char**)':
total.cpp:37: request for member `setdata' in `ob', which is of non-aggregate
type `counter*'
total.cpp:39: request for member `getdata' in `ob', which is of non-aggregate
type `counter*'


what does the error mean ?

ob is a counter * (pointer to counter) so to access the member functions you use the -> member selection operator, e.g.

ob->setdata(10);
cout<<ob->getdata();
