Pointers and references are not so different that they need separate names. Please perform pointer arithmetic or demonstrate the pointer/array equivalence with references or write a garbage collection system which uses pointer counting. When you've finished, demonstrate effective and type-safe autovivification with pointers. Finally, use references (sorry, pointers) to stack-allocated variables in C and create an object system based on closures.
