Why Use Pointers?

The main reasons to use pointers are:

To assign a variable from another function

To modify a variable from a member function

To manage copy on function call
Strongly disagree. Those are all things pointers can be used for, but they’re all relatively incidental. The overwhelmingly most important reason for the existence of pointers: data structures.

Actually it is not specific to pointer, any reference mechanism should be able to do the same, for example python objects ar list.
