The arrays are heterogeneous: a single array can have keys of different types. PHP's associative arrays can be used to represent trees, lists, stacks, queues, and other common data structures not built into PHP. An associative array can be declared using the following syntax:
In Lisp, lists are the fundamental data type and can represent both program code and data. In most dialects, the list of the first three prime numbers could be written as (list 2 3 5) . In several dialects of Lisp, including Scheme , a list is a collection of pairs, consisting of a value and a pointer to the next pair (or null value), making a ...
The disadvantage of association lists is that the time to search is O(), where n is the length of the list. [3] For large lists, this may be much slower than the times that can be obtained by representing an associative array as a binary search tree or as a hash table.
A browser window allows the user to view and navigate through a collection of items, such as files or web pages. Web browsers are an example of these types of windows. Text terminal windows present a character-based, command-driven text user interfaces within the overall graphical interface. MS-DOS and Unix consoles are examples of these types ...
A translator generates C source code and the GNU compiler collection (GCC) and Open Watcom compilers are supported. Alternatively, Euphoria programs may be bound [7] with the interpreter to create stand-alone executables. A number of graphical user interface (GUI) libraries are supported including Win32lib [8] and wrappers for wxWidgets, [9 ...
Property list files use the filename extension.plist, and thus are often referred to as p-list files. Property list files are often used to store a user's settings. They are also used to store information about bundles and applications , a task served by the resource fork in the old Mac OS.
The programmer writes an interface file containing a list of C/C++ functions to be made visible to an interpreter. SWIG will compile the interface file and generate code in regular C/C++ and the target programming language.
The GUI of a program is commonly constructed in a cascading manner, with graphical control elements being added directly to on top of one another. Most widget toolkits use event-driven programming as a model for interaction. [1] The toolkit handles user events, for example when the user clicks on a button. When an event is detected, it is ...
