C++ pointers - application

Question

Can anyone share a practical application or a case study for C++ pointers?

I'm going through that section in the c++ course and I'm finding it hard to picture a scenario where one would mess with pointers and memory addresses

Answer 1

I would say pointers are more common in API's. When you give a user the control to create a product using your API, it is an absolute must to use pointers, because everything the user creates is a dynamic allocation of a class defined in the API.
