mapping

1.  (Or "map", "mapping") If D and C are sets
(the domain and codomain) then a function f from D to C,
normally written "f : D -> C" is a subset of D x C such that:

1. For each d in D there exists some c in C such that (d,c) is
an element of f.  I.e. the function is defined for every
element of D.

2. For each d in D, c1 and c2 in C, if both (d,c1) and (d,c2)
are elements of f then c1 = c2.  I.e. the function is uniquely
defined for every element of D.

2.  Computing usage derives from the mathematical
term but is much less strict.  In programming (except in
functional programming), a function may return different
values each time it is called with the same argument values
and may have side effects.

A procedure is a function which returns no value but has
only side-effects.  The C language, for example, has no
procedures, only functions.  ANSI C even defines a type,
void, for the result of a function that has no result.
