Why does a C + + class use pointers

The question turns out to be this:

C + + objects are different from C #, where C + + objects are placed on the stack, and C # objects are reference types.

This means that when C + + is converting, the object discards some of the information since the copy constructor is called.

When a derived class becomes a base class, it can no longer be changed back .....

C # is using reference types

C + + is the semi-finished product of C #, don't expect those advanced features C + + on C #. C + + is a low-level language that must be re-learned.
