Perl 5.6.1 and newer support autovivification of file and directory handles. [3] Calling open() on an undefined variable will set it to a filehandle. According to perl561delta, "[t]his largely eliminates the need for typeglobs when opening filehandles that must be passed around, as in the following example:
/* This class has two type variables, T and V. T must be a subtype of ArrayList and implement Formattable interface */ public class Mapper < T extends ArrayList & Formattable, V > {public void add (T array, V item) {// array has add method because it is an ArrayList subclass array. add (item);}}
Note how the use of A[i][j] with multi-step indexing as in C, as opposed to a neutral notation like A(i,j) as in Fortran, almost inevitably implies row-major order for syntactic reasons, so to speak, because it can be rewritten as (A[i])[j], and the A[i] row part can even be assigned to an intermediate variable that is then indexed in a separate expression.
In computer science, a dynamic array, growable array, resizable array, dynamic table, mutable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern mainstream programming languages.
An Array is a JavaScript object prototyped from the Array constructor specifically designed to store data values indexed by integer keys. Arrays, unlike the basic Object type, are prototyped with methods and properties to aid the programmer in routine tasks (for example, join, slice, and push).
^c Subranges are used to define the bounds of the array. ^d JavaScript's array are a special kind of object. ^e The DEPENDING ON clause in COBOL does not create a true variable length array and will always allocate the maximum size of the array.

When one object changes state, an open-ended number of dependent objects should be updated automatically. An object can notify multiple other objects. Defining a one-to-many dependency between objects by defining one object (subject) that updates the state of dependent objects directly is inflexible because it couples the subject to particular ...
