Then, in a second step, introduce variables of type "pointer".


Where "pointer" does not only mean, that such variables contain
addresses, that's just a convention. You also must open the can of
worms, by allowing access to memory locations, using the *values* stored
in pointer variables, and by introducing pointer arithmetic, so that
references can end up in some variable near the variable pointed to, or
in unallocated memory.


Pointers are harmless, unless they are used. Then they establish worm
holes throughout your universe, or even out of it ;-)
