Problem Statement

In this task, the goal is to demonstrate common operations on pointers and references. These examples show pointer operations on the stack, which can be dangerous and is rarely done. Pointers and references are commonly used along with Memory allocation on the heap.

Let's start with the solution:

val p = ref 1; (* create a new "reference" data structure with initial value 1 *)
val k = !p;    (* "dereference" the reference, returning the value inside *)
p := k + 1;    (* set the value inside to a new value *)
