for (name in phonebook) {print name," ", phonebook [name]} The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
var name «: type»« = initial_value» let name «: type» = value: typealias synonym = type: Common Lisp (defparameter name initial-value) or (defvar name initial-value) (defconstant name value) (deftype synonym 'type) Scheme (define name initial_value) ISLISP (defglobal name initial_value) or (defdynamic name initial_value) (defconstant name ...
The disadvantage of this fine-grained control is a complicated syntax, but, because all generic formal parameters are completely defined in the specification, the compiler can instantiate generics without looking at the body of the generic. Unlike C++, Ada does not allow specialised generic instances, and requires that all generics be ...

[3] [10] Another very simple implementation technique, usable when the keys are restricted to a narrow range, is direct addressing into an array: the value for a given key k is stored at the array cell A[k], or if there is no mapping for k then the cell stores a special sentinel value that indicates the lack of a mapping. This technique is ...
C++/WinRT was introduced as part of the Microsoft Windows SDK in version 10.0.17134.0 (Windows 10, version 1803) and is a component of Windows App SDK (formerly known as Project Reunion). Microsoft Visual Studio support for C++/WinRT is provided by an officially-supported extension.
Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.

The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
