i have a class called Employee and a method in that class called display(). When that method is called it displays a first name and a last name.
In my int main() i have...
I was wondering if there were a way to have the pointer point to emp and then use the pointer to display emp as opposed to simply saying...
if this is possible how would i do it?
Thanks for the help

Well yes its possible, but why would you want to do it? Unless, of course you are passing a pointer to another function.

one purpose of pointers to to allocate an array of something because the size is not known until the program is run.
Another purpose: creating a linked list of Employee classes. Admittedly most c++ programmers would using c++ container classes such as vector or dqueue.
Employee* empArray = new Employee[NumberEmployees]; Another purpose: creating a linked list of Employee classes. Admittedly most c++ programmers would using c++ container classes such as vector or dqueue.
