The first is or could be Haskell. The length of a list is not part of its type. The second looks like Java, ditto there (although built-in arrays have a different syntax). Haskell does not have mutability at all and thus no "pointers". In Java the insides of containers are mutable so you'd have to add an outer array or list. In either case though you don't need pointers to simply pass things around as you do in C (I don't know about Go).
