lists

    This subchapter looks at lists.

functions

LISP    ATOM(x) — LISP predicate function that takes one argument of type s-list and returns whether or not the argument is an atom. ATOM returns T if the argument is an ATOM and returns NIL if the argument is not an atom.

LISP    APPEND(x) — LISP function that takes zero or more arguments of type list and creates a list that has those component lists in the designated order. Note in the example of APPEND '((A) (B)) ;((C) (D))) that APPEND returns ((A) (B) (C) (D)) rather than (A B C D).

LISP    ARG(x) — LISP function that takes one arguments of type fixed point number (as an index into a list) and extracts the desired argument from a list.

LISP    APPLY(x) — LISP function that takes two or three arguments of type function, type argument list, and optional type environ, and applies the designated function to the designated list.

Ada

    “36 Access types allow the construction of linked data structures. A value of an access type represents a reference to an object declared as aliased or to an object created by the evaluation of an allocator. Several variables of an access type may designate the same object, and components of one object may designate the same or other objects. Both the elements in such linked data structures and their relation to other elements can be altered during program execution. Access types also permit references to subprograms to be stored, passed as parameters, and ultimately dereferenced as part of an indirect call.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary See legal information

    “42.1/2 The predefined standard library packages provide facilities such as string manipulation, containers of various kinds (vectors, lists, maps, etc.), mathematical functions, random number generation, and access to the execution environment.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary See legal information

   “Pointers also require sensible notation. np is just as mnemonic as nodepointer if you consistently use a naming convention from which np means “node pointer” is easily derived.” —Rob Pike, Notes on Programming in C, February 21, 1989


free music player coding example

    Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

    Create your own copy from the original source code/ (presented for learning programming).
