C++'s std::vector and Rust's std::vec::Vec are implementations of dynamic arrays, as are the ArrayList [25] classes supplied with the Java API [26]: 236 and the .NET Framework. [27] [28]: 22 The generic List<> class supplied with version 2.0 of the .NET Framework is also implemented with dynamic arrays.
Lists are typically implemented either as linked lists (either singly or doubly linked) or as arrays, usually variable length or dynamic arrays.. The standard way of implementing lists, originating with the programming language Lisp, is to have each element of the list contain both its value and a pointer indicating the location of the next element in the list.
Let us recall that, for a list l, |l| denotes its length, that NIL represents an empty list and CONS(h, t) represents the list whose head is h and whose tail is t. The functions drop(i, l) and take(i, l) return the list l without its first i elements, and the first i elements of l, respectively. Or, if |l| < i, they return the empty list and l ...
Function rank is an important concept to array programming languages in general, by analogy to tensor rank in mathematics: functions that operate on data may be classified by the number of dimensions they act on. Ordinary multiplication, for example, is a scalar ranked function because it operates on zero-dimensional data (individual numbers).
Thus, if the array is seen as a function on a set of possible index combinations, it is the dimension of the space of which its domain is a discrete subset. Thus a one-dimensional array is a list of data, a two-dimensional array is a rectangle of data, [12] a three-dimensional array a block of data, etc.
Quite contrary to C++, in the functional programming language Haskell the void type denotes the empty type, which has no inhabitants . A function into the void type does not return results, and a side-effectful program with type signature IO Void does not terminate, or crashes. In particular, there are no total functions into the void type.
